The blood-glucose level begins to drop several hours after a meal, leading to a decrease in insulin secretion and a rise in glucagon secretion; glucagon is secreted by the α cells of the pancreas in response to a low blood-sugar level in the fasting state. In same way,insulin signals the fed state, this fed condition leads to the secretion of insulin, which is one of the two most important regulators of fuel metabolism,the secretion of the hormone insulin by the β cells of the pancreas is stimulated by glucose. It stimulates glycogen synthesis in both muscle and the liver and suppresses gluconeogenesis by the liver.
What else can I help you with?
Is glucose the basic unit of glycogen?
Glucose is the basic unit of glycogen. In humans, glycogen is stored in the liver as well as the muscle tissues.
Liver cells and muscle are able store chains of glucose in a molecule are call?
Liver cells store chains of glucose in a molecule called glycogen, while muscle cells store glucose in the form of glycogen as well. Glycogen acts as a reserve of energy that can be broken down into glucose when needed for energy production.
How during a marathon race the blood glucose concentration stays fairly constant but the mass of glycogen in the liver decreases?
During a marathon, the body primarily uses glycogen stored in the liver and muscles for energy. As the race progresses, glycogen stores deplete, leading to a decrease in liver glycogen levels. However, blood glucose concentration remains relatively constant due to the liver's ability to release glucose into the bloodstream through gluconeogenesis and glycogenolysis, as well as the hormonal regulation of insulin and glucagon. This mechanism ensures that the muscles continue to receive a steady supply of glucose for energy, despite the declining glycogen reserves.
How do you remember glycogen and glucagon?
Glycogen is a form of stored glucose in the body, primarily found in the liver and muscles. Glucagon is a hormone that helps release glucose from glycogen when blood sugar levels are low, providing energy for the body. Think of glucagon as "glucose-gone" - it helps to release glucose when it's gone.
What is the function of glycogen granules in animal cell?
Glycogen granules form an energy or food store in mammalian cells. When needed, the glycogen can be broken down (hydrolysed) into glucose, which is used in respiration as a source of energy for the cell. For some background see: http://www.sciencedaily.com/articles/g/glycogen.htm
Where do we have a small store of glycogen?
Glycogen is stored in the liver and muscles in the human body. The liver typically stores about 100g of glycogen, while the muscles can store varying amounts depending on muscle mass and exercise level.

Liver cells store chains of glucose in a molecule called glycogen, while muscle cells store glucose in the form of glycogen as well. Glycogen acts as a reserve of energy that can be broken down into glucose when needed for energy production.
How much glycogen can the liver store?
All together the avg. human can store approx. 500-600g of glycogen. Skeletal muscle holds twice that of the liver,, so approx. 200g for the liver and 400g for the muscle. In endurance type sports like cycling at 70%vo2max this equates to about 2 - 2.5hrs of exercise before glycogen depletion but this varies from individual to individual based on how well trained the athlete and the training protocols used. It is interesting to note that the body places a pref on liver glycogen over muscle glycogen during prolonged exercise and that fasted exercising increases overall glycogen storage capacity. whether in the muscle alone or liver or both is uncertain.
How do you remember glycogen and glucagon?
Glycogen is a form of stored glucose in the body, primarily found in the liver and muscles. Glucagon is a hormone that helps release glucose from glycogen when blood sugar levels are low, providing energy for the body.

What chemical enzyme breaks down what nutrient in the liver?
I believe you're referring to the hormone glucagon produced by the alpha cells in the pancreas which causes the liver to break down glycogen. There are no nutrients stored in the liver, the liver stores bile as well as lipase, neither of which are considered "nutrients"

What are the characteristics of glycogen?
Glycogen is a polysaccharide that is the principal storage form of glucose (Glc) in animal and human cells. Glycogen is found in the form of granules in the cytosol in many cell types. Hepatocytes (liver cells) have the highest concentration of it - up to 8% of the fresh weight in well fed state, or 100-120 g in an adult. In the muscles, glycogen is found in a much lower concentration (1% of the muscle mass), but the total amount exceeds that in liver. Small amounts of glycogen are found in the kidneys, and even smaller amounts in certain glial cells in the brain and white blood cells. Glycogen plays an important role in the glucose cycle
Do bones provide reserves of Glycogen?
No, bones do not provide reserves of glycogen. Glycogen is stored in the liver and muscles, not in bones. Bones are primarily responsible for providing structure and support to the body, as well as producing blood cells and storing minerals like calcium and phosphorus.
The chemical process of building glycogen from glucose molecules?
Glycogen is synthesized by the enzyme glycogen synthase, which adds glucose molecules together to form a long chain of glycogen. This process requires energy in the form of ATP and occurs primarily in the liver and muscles when blood glucose levels are high. Glycogen serves as a storage form of glucose for the body to use when needed.
What does a cows liver do?
it kills bacteriaAnother answerI presume you mean what does the liver do for the chicken, rather than what does it do for the rest of the meal. Well, livers are not there to kill bacteria. They have a number of functions in the body, including glycogen storage, decomposition of red blood cells, plasma protein synthesis, hormone production, and detoxification and production of bile.
Differences between the rates of reaction with potato as compared to liver?
Well potatoes have less protein than the liver therefore the liver reacts faster with more protein than the potato which is all starch.
