glycogen
No, insulin stimulates the liver to produce glycogen from glucose. Glucagon mobilizes liver glycogen to yield glucose.
The hormone glucagon stimulates the liver to release glucose into the blood when glucose levels are low.
Glucagon is a hormone produced by the pancreas that stimulates the liver to break down glycogen into glucose. By doing so, the endocrine system increases the blood sugar level.
The hormone Insulin regulates the body's glucose levels.
* Insulin - released by pancreas - encourages liver and muscle cells to absorb glucose from the blood; stimulates the conversion of glucose ----> glycogen in liver/muscle cells.
The hormone that promotes glucose formation in the liver is glucagon. It is secreted by the alpha cells of the pancreas when blood glucose levels are low. Glucagon stimulates gluconeogenesis and glycogenolysis in the liver, leading to increased glucose release into the bloodstream. This helps to elevate blood glucose levels and maintain energy balance in the body.
An example of homeostasis is regulating blood glucose concentration. The body does this as follows: If there is enough glucose in the blood, the hormone insulin (from the pancreas) stimulates the liver to store the extra (not needed at the time) glucose as glycogen. If the blood sugar gets low, another hormone stimulates the liver to release the glucose back into the blood. If the storage in the liver is full, glucose is converted into fat in special cells around the body.
gluconeogenesis
Glucagon is the hormone that stimulates gluconeogenesis in the liver by increasing the breakdown of glycogen into glucose, promoting the formation of new glucose molecules.
Triglyceride
No. Unlike skeletal muscles, the liver contains an enzyme known as glucose 6-phosphatase that can remove the phosphate groups and produce free glucose.
When blood sugar levels are low the pancreas will secrete glucagon which will stimulate the liver to breakdown glycogen (our reserve sugar supply) and stimulate gluconeogenesis which is converting fats and proteins into glucose (blood sugar).
