Insulin and Glucagon | Biology for All | FuseSchool
In this lesson, you will learn about how your blood glucose level is regulated (or controlled) by two important hormones – insulin and glucagon, via a negative feedback system. When you consume a meal that is high in carbohydrates, such as rice, pasta, and bread, this will cause your blood glucose level to increase. Carbohydrates are essentially long chains of repeating glucose monomer units, much like beads on a necklace. During digestion, this is broken apart into glucose, which absorbed into our bloodstream. This increased blood glucose level causes a gland known as the pancreas to secrete a hormone called insulin. Remember that a gland secretes hormones which act on specific target organs. In this case, the target organ is your liver, which is stimulated to convert glucose to glycogen. Glycogen is basically long, multi-branched chains of glucose monomers, stored in liver and muscle cells. Insulin also causes your body cells to uptake (or take in) glucose. So this decreases your blood glucose level back to its optimal state. When this system is faulty, this leads to a medical condition known as diabetes – If you want to learn more about diabetes, this will be addressed in another video. The same response also occurs when you consume foods and drinks high in sugar such as sweets, cakes, and fizzy drinks. When your blood glucose level drops, such as when you are hungry, the pancreas secretes a hormone called glucagon. Like insulin, the target organ for glucagon is also the liver, though it stimulates the opposite process – the breakdown of glycogen into glucose. This increases your blood glucose level back to its optimal state. So to review, insulin and glucagon are two hormones released by the pancreas, which act on the liver to regulate our blood glucose level.

Diabetes Mellitus 2 of 6 (Regulation of blood Glucose by Insulin)
Insulin is the principal hormone that regulates the uptake of glucose from the blood into most cells of the body, especially liver, muscle, and adipose tissue. Therefore, deficiency of insulin or the insensitivity of its receptors plays a central role in all forms of diabetes mellitus. The body obtains glucose from three main places: the intestinal absorption of food, the breakdown of glycogen, the storage form of glucose found in the liver, and gluconeogenesis, the generation of glucose from non-carbohydrate substrates in the body.[ Insulin plays a critical role in balancing glucose levels in the body. Insulin can inhibit the breakdown of glycogen or the process of gluconeogenesis, it can stimulate the transport of glucose into fat and muscle cells, and it can stimulate the storage of glucose in the form of glycogen. Insulin is released into the blood by beta cells (β-cells), found in the islets of Langerhans in the pancreas, in response to rising levels of blood glucose, typically after eating. Insulin is used by about two-thirds of the body's cells to absorb glucose from the blood for use as fuel, for conversion to other needed molecules, or for storage. Lower glucose levels result in decreased insulin release from the beta cells and in the breakdown of glycogen to glucose. This process is mainly controlled by the hormone glucagon, which acts in the opposite manner to insulin.

The Role of Insulin in the Human Body
Developed and produced by http://www.MechanismsinMedicine.com Animation Description: This patient-friendly animation describes the main role of insulin in the human body. When food is ingested, it travels along the digestive tract where it is broken down into its component nutrients in order to be absorbed into the bloodstream. One such nutrient is glucose, a simple sugar. Glucose gets absorbed by the stomach and intestines and then enters the bloodstream. It travels through the circulation to all body cells. Once absorbed into the bloodstream, glucose circulates causing the blood sugar level to rise. An increased level of blood sugar sends a signal to the pancreatic beta cells, which respond by secreting the hormone insulin into the circulation. Insulin is necessary for glucose to reach and be used by several important target tissues throughout the body. These include the liver, muscle, and adipose tissue. Insulin is necessary to keep blood glucose levels stable in the body. Circulating insulin binds to specific insulin receptors located on the cell membrane of tissue cells throughout the body. Upon binding, a signal is sent to the nucleus of the cell, instructing it to transport glucose channels to the cell surface. These channels allow glucose to enter the cell. Glucose enters the cell through a process called facilitated diffusion.

How To Lower Blood Sugar Immediately
You can find Sensolin here: https://www.truthnutra.com/sensolin-yt In the next 60 seconds I'm going to show how to lower blood sugar immediately and naturally increase insulin sensitivity. So first off, let's take a look at… What is insulin? Insulin is a hormone that's produced by the pancreas, that helps turn sugars from carbohydrates to energy. It also allows the body to store glucose for future use. The muscles and liver store the sugars as glycogen, which causes muscle cells to expand. Likewise, fat cells store the sugar as triglycerides and may expand as well. Now, what is insulin sensitivity, and insulin resistance. Insulin sensitivity is how receptive the body is to the insulin it produces. When the body is properly sensitive to insulin, it uses that insulin produced and effectively removes it from the bloodstream, making energy and storing glucose for later. A healthy body is sensitive to insulin, which means it needs to make less insulin to stay healthy. Better yet, being more insulin sensitive allows the body to utilize carbohydrates properly for more energy, building muscle, and will also help the body store less fat. What's even better, is that greater insulin sensitivity is going to lead to higher T levels in men. Now what are some signs that a person might have poor insulin sensitivity? Or have developed insulin resistance? Higher insulin levels can cause weight gain, higher insulin levels can cause aging, higher insulin levels can cause reduced T, higher insulin levels increases cravings for junk foods, and also leads to blood pressure issues. With all of this in mind, for anyone who feels as though they're one of those people who is constantly riding the blood sugar roller coaster, with blood sugar all over the place, depending on what you eat, when you eat, and you get hangry and get crazy when they don't have food, For everyone who needs help with blood sugar control and needs to increase their insulin sensitivity naturally, and for the good people out there who don't want to go take drugs to achieve this, I've got 3 natural compounds to use today to simply, and quickly increase insulin sensitivity naturally and get control over those cravings once again. Now the first thing is what's known as berberine. Now berberine is an alkaloid extract taken from various plants and it's been used in traditional chinese medicine for centuries. Some of the benefits of berberine include, anti-inflammatory and antidiabetic effects, improved intestinal health, improved cholesterol numbers, increased exercise performance, and decreased blood pressure. Now the recommended dosage for berberine is between 500-1500mg/day. It's also recommended to take this dosage split between 2-3 times throughout the day. Now next up, we have cinnamon ceylon oil. Cinnamon is commonly used as a spice but it's also known for its numerous biological effects on the body. The best type of cinnamon is ceylon because it has lower coumarin content. Cinnamon has a ton of benefits, including reducing the rate at which glucose enters the body, improved glucose usage in cells, lower fasting blood sugar, and improved cholesterol levels. Now the recommended dosage for daily cinnamon intake is between 1-6g per day. And the third compound, the third natural ingredient that you can consume on a daily basis is actually what's known as chromium. Chromium is an essential mineral that's consumed through your diet. It's found in plant products and grains. The benefits of chromium include, a regulation of glucose metabolism, improved insulin sensitivity, it is used to treat glucose intolerance in type 2 diabetes, leads to a great reduction in appetite, improved symptoms of depression, and a noticeable increase in libido with the right amount of chromium. Now the daily recommended dosage of chromium is between 800-1000 mcg. At this point, some of y'all are probably wondering: where do we get all these things? One option is to search around on Amazon and try to find them, but we did at Truth Nutra is that we put together a supplement known as Sensolin (hold up sensolin bottle). Sensolin is specifically designed with these three ingredients at the exact clinical dosages shown in human studies to actually work, to actually help regulate blood glucose and to help with insulin sensitivity. Now we put them all in here, it's a very simple supplement. And it actually works.

5.3 Carbohydrates: Blood Glucose Regulation
Lecture on blood glucose regulation. Starch is digested to maltose and glucose, glucose is absorbed increasing blood glucose levels. The pancreas responds with insulin, driving glucose out of the bloodstream into the cells (particularly the muscle and fat cells). As glucose leaves the bloodstream, this lowers blood glucose levels, normalizes blood glucose. When a meal is skipped, blood glucose drops and this stimulates the pancreas to release glucagon, glucagon stimulates the liver to release glycogen (our storage form of glucose) which breaks down to glucose. When glucose enters the bloodstream, it elevates blood glucose levels. For more information on carbohydrates, visit http://www.nutritionaldoublethink.com/carbohydrates.html

Normal regulation of blood glucose
The human body wants blood glucose maintained in a very narrow range. Insulin and glucagon are the hormones which make this happen. Both insulin and glucagon are secreted from the pancreas, and thus are referred to as pancreatic endocrine hormones. It is the production of insulin and glucagon by the pancreas which ultimately determines if a patient has diabetes, hypoglycemia, or some other sugar problem. Role of Insulin in blood glucose control Insulin and glucagon are hormones secreted by islet cells within the pancreas. They are both secreted in response to blood sugar levels, but in opposite fashion! Insulin is normally secreted by the beta cells of the pancreas. The stimulus for insulin secretion is a HIGH blood glucose. Although there is always a low level of insulin secreted by the pancreas, the amount secreted into the blood increases as the blood glucose rises. Similarly, as blood glucose falls, the amount of insulin secreted by the pancreatic islets goes down. Insulin has an effect on a number of cells, including muscle, red blood cells, and fat cells. In response to insulin, these cells absorb glucose out of the blood, having the net effect of lowering the high blood glucose levels into the normal range. Glucagon is secreted by the alpha cells of the pancreatic islets in much the same manner as insulin...except in the opposite direction. If blood glucose is high, then no glucagon is secreted. When blood glucose goes LOW, however,more and more glucagon is secreted. Like insulin, glucagon has an effect on many cells of the body, but most notably the liver. The Role of Glucagon in Blood Glucose Control The effect of glucagon is to make the liver release the glucose it has stored in its cells into the bloodstream, with the net effect of increasing blood glucose. Glucagon also induces the liver to make glucose out of building blocks obtained from other nutrients found in the body. Our bodies desire blood glucose to be maintained between 70 mg/dl and 110 mg/dl . Below 70 is termed "hypoglycemia." Above 110 can be normal if you have eaten within 2 to 3 hours. That is the reason of determining fasting blood sugar.Normally it should be between 70-110 mg/dl. Even after you have eaten, however, your glucose should be below 180. Above 180 is termed "hyperglycemia". If your 2 blood sugar measurements above 200 after drinking a sugar-water drink (glucose tolerance test), then you are diagnosed with diabetes.

https://goo.gl/31T06Y to unlock the full series of AS, A2 & A-level Biology videos created by A* students for the new OCR, AQA and Edexcel specification. We pick up where we left off last time and look at the case when blood glucose drops too low, talking through the mechanism of action of glucagon when released from the alpha cells in the islets of Langerhans. We’ll also talk through how the regulation of blood glucose levels is achieved through the antagonistic effects of insulin and glucagon which act through a system of negative feedback, before tackling an exam style question.

What Is High Blood Sugar Levels - Blood Glucose Levels Explained - Normal Sugar Level In Blood
In this video I discuss what is blood sugar level, and what causes high and low blood sugar levels. We also look at insulin's role in blood sugar levels, and some of the risk factors for developing type 2 diabetes. Transcript (partial) In this video we are going to discuss what blood sugar or blood glucose is, and why it is important. Blood sugar level is the amount of glucose(sugar) present in the blood. Our body gets glucose from some of the foods we eat. After the digestive process, the liver releases glucose into the bloodstream, sending it to cells to be used as energy. As glucose is released into the bloodstream, blood sugar levels rise. This triggers the pancreas to release the hormone insulin, which tells the cells to open up and let the glucose in, which lowers blood sugar levels. Excess glucose is stored as glycogen in the muscles and liver. This process happens many times throughout the day after we eat. A normal fasting (no food for 8 hours) blood sugar level is between 70 and 99mg/dl, and a normal level two hours after eating is less than 140mg/dl. So, why is this important? Well, there are 3 main reasons we need to be aware of our blood sugar level. The 1st reason is that high blood sugar levels can lead to type 2 diabetes. Type 2 diabetes is when the body doesn’t use insulin properly (insulin resistance), or when the pancreas stops producing enough insulin. Over time, High blood sugar levels can put a lot of stress on the pancreas, possibly causing it to become permanently damaged. 95% of all diabetes cases in the US are type 2. Researchers don't fully understand why some people develop type 2 diabetes and others don't. However, there are some factors that increase the risk. -being overweight – the more fatty tissue you have, the more resistant your cells become to insulin. -fat distribution – more fat storage in the abdomen increases the risk -inactivity - Physical activity helps you control your weight, uses up glucose as energy and makes your cells more sensitive to insulin. The 2nd reason we need to monitor our blood sugar levels is that High levels can also lead to atherosclerosis, which is hardening and narrowing of the arteries. This can block the arteries, putting blood flow at risk, which can lead to other problems. The 3rd reason is low blood sugar levels, this is rare in non-diabetics. This can be caused by certain medications, excessive alcohol consumption, excessive exercise, and from meals high in refined carbs.

How to Treat and Bring Down High Blood Sugar Levels
Are your blood sugar levels high? Are your eating habits healthy? What about your weight? Is it average or above average? Did you know that if you’re overweight, and you have unhealthy eating habits, you could be one of the victims of diabetes? Diabetes is a disease that affects almost 400 million people in all the world, slightly more than 5% of the population. Type 2 diabetes is the most common form of the disease, and is linked to weight gain and bad eating habits. Fortunately, diabetes is not a silent threat. Learn more about the symptoms of diabetes to know if you are in this situation: Extreme thirst Extreme hunger Fatigue Wounds may take longer to heal Blurry vision Low Immunity Diabetes is a disease that springs from a sedentary lifestyle, paired with poor eating habits and lack of frequent exercise. Depressed people who spend large amounts of time sleeping are also more likely to suffer from this disease. The best protection against diabetes are healthy eating habits. Choose to eat less sugar and carbohydrates. Here are some recipes that can help improve your condition: Onion and Lemon Broth Squeeze the juice of a grated onion through a thin cloth. Mix that juice with the juice of one lemon. Drink this twice a day. Test your blood sugar and cholesterol levels regularly to see how you’re doing. Raw Garlic and in Pills Garlic has many and varied benefits, and is used to treat, fight, and prevent several diseases. Recent studies have shown that garlic can increase insulin production, a hormone that turns glucose into energy and controls type 2 diabetes. Furthermore, consuming large quantities of raw garlic reduces blood sugar levels. How to use Garlic In order to benefit from garlic, you need to eat raw garlic regularly. Remember that garlic, after it has been warmed up, loses most of its beneficial properties. If the taste keeps you from being able to eat it, you can take garlic pills or garlic oil. You should consume from 500 milligrams to 1000 milligrams of garlic a day, which adds up to 1 or 2 fresh, raw garlic cloves. Another alternative would be drinking “garlic water”. Pour 200 milliliters of water in a cup and add one minced clove of garlic. Let it sit so that the garlic's properties can be absorbed into the water, and drink it throughout the day. At the end of the day, throw the garlic away. Remember that if you eat too much garlic you may suffer from some digestive problems. These recipes are not recommended for people who are allergic to garlic, pregnant, or breastfeeding women, or children under the age of 4.

Regulation of glycogen metabolism | Glycogen metabolism lecture 3
Regulation of glycogen metabolism - This lecture explains about how the glycogen metabolism is regulated in cell with Hormones like insulin and glucagon and epinephrine. Here we will see the mechanism of insulin in controlling the blood glucose level by converting blood glucose into glycogen and store in the liver and it also states how glucagon secretion helps in the degradation of the glycogen into glucose so that energy can be produced from it. So watch this biochemistry lecture to understand about the regulation of glycogen synthesis and glycogen breakdown.

Blood glucose control and diabetes

When glucose levels in the blood rise the pancreas secretes insulin, which tells the liver to convert glucose to glycogen and store it, thus returning glucose levels back to normal. When glucose levels fall, the pancreas recognises this change and secretes glucagon. Glucagon is a hormone that causes the liver to convert glycogen to glucose and release it, thus raising the blood glucose level back to normal. A person with diabetes doesn’t have an effective mechanism for blood glucose control. Type 1 diabetes is when the immune system attacks the cells in the pancreas that secrete insulin. Type 2 diabetes is when the bodies cells don’t respond correctly to insulin.

If in the US use this link http://goo.gl/mDMfj5 If in the UK use this link http://goo.gl/j0htQ5 It is essential that blood glucose concentrations are maintained at relatively constant levels. Glucose is the only form of sugar found in the blood. If other sugars, such as fructose or galactose, are absorbed from the gut, the liver quickly converts them into glucose. If there is too much glucose in the blood this will damage several body tissues, however if there is not enough, cells will not be able to use glucose as a fuel in the mitochondria. High blood glucose levels are referred to as hyperglycaemia and low levels as hypoglycaemia. Some MCQs to think about..... The beta cells in the pancreas produce; (Choose one option) a. Insulin b. Glucagon c. Thyroid hormone d. Glucose Which of the following are functions of insulin? (Choose one option) a. Converts glucose to glycogen b. Converts glycogen to glucose c. Converts fats into ketones d. Converts proteins into amino acids Which of the following are functions of insulin? (Choose one option) a. Raised blood sugar levels b. Lowers blood sugar levels c.
