Insulin causes the glucose in your blood to enter the cells for energy. It does not cause the liver to change glucose into anything. Your liver does, however, store extra sugar in the form of glucagon.
Insulin is the hormone that promotes the storage of glucose by the liver. It signals liver cells to take up glucose from the bloodstream and convert it into glycogen for storage.
No, insulin stimulates the liver to produce glycogen from glucose. Glucagon mobilizes liver glycogen to yield glucose.
Insulin
Insulin signals blood cells like liver and muscle cells. These are used to accelerate the conversion of glucose to glycogen that's stored in the liver. Glucagon attach themselves to liver cells telling them to convert glycogen to glucose and to release glucose into the blood.
No, it is the beta cells of the pancreas that produce the hormone insulin, involved in glucose uptake by cells.
GlucagonINSULIN causes glucose to be removed from the blood stream by having it stored in the form of Glycogen in muscle and liver cellsGLUCAGON causes glycogen to be broken down from liver and muscle tissue and releases glucose into the blood stream, thus increasing circulating blood glucose levels. The hormone, released by the pancreas, is insulin.
Insulin promotes the storage of glucose as glycogen in the liver and muscles by stimulating glycogen synthesis. When blood glucose levels are high, insulin is released from the pancreas to signal cells to take up glucose and convert it into glycogen for storage.
Insulin enables the sugar to get out of the blood and into the cells where it is needed for the cells to function. If you don't have insulin because the pancreas is not producing it (as in diabetes) then the sugar will not be able to get into the cells, therefore there will be a high concentration in the blood. On the other hand, if you are diabetic and you take too much insulin, then too much sugar will go into the cells and there will not be enough sugar left in the blood.
During exercise, changes in insulin concentration can affect glucose mobilization by stimulating glucose uptake in muscles. When insulin levels decrease during fasting or intense exercise, there is reduced inhibition of glycogen breakdown and increased release of glucose from the liver to maintain blood glucose levels. Conversely, high insulin levels during rest or fed state promote glucose uptake by tissues, decreasing reliance on liver glucose release.
To create a flow chart illustrating how insulin and glucagon maintain blood glucose levels, start with "Increased Blood Glucose" leading to "Pancreas Releases Insulin," which prompts "Cells Take Up Glucose" and "Liver Stores Glucose as Glycogen." Conversely, from "Decreased Blood Glucose," draw an arrow to "Pancreas Releases Glucagon," which results in "Liver Converts Glycogen to Glucose" and "Glucose Released into Blood." This flowchart shows the opposing actions of insulin and glucagon in regulating blood sugar levels.
Insulin
The body maintains blood glucose levels through a balance of insulin and glucagon hormones. When blood sugar is high, insulin is released to promote glucose uptake by cells and storage in the liver. On the other hand, when blood sugar is low, glucagon is released to stimulate the liver to release stored glucose into the bloodstream.
