What Converts Glycogen To Glucose
Why did I only get 1/2 a mark for this answer?
My answer:
Insulin controls the level of glucose in the blood stream by converting it to glycogen. Insulin is produced in the pancreas rapidly from about 15 minutes after feeding because it takes this time for glucose to reach the blood stream. Insulin goes on being produced for as long as food is absorbed into the bloodstream and after 150 minutes its concentration shows that nutrients must still be entering the blood from the small intestine.
Question:
I was told to ‘Briefly explain the function of insulin. its plasma concentration began to rise almost immediately after feeding and very rapidly after about 15 minutes. What could be responsible for these two changes in secretion rate and why might plasma insulin levels have remained above initial levels some 150 minutes after feeding.
sorry to be annoying but this makes the difference [lol] to my mark!!
Regulation of insulin secretion
Insulin secretion is increased by:
* elevated blood glucose concentrations
* gastrointestinal hormones
* Beta adrenergic stimulation
Insulin secretion is inhibited by:
* catecholamines
* somatostatin
The role of insulin and glucagon in glucose metabolism
Insulin and glucagon work synergistically to keep blood glucose concentrations normal.
Insulin
An elevated blood glucose concentration results in the secretion of insulin: glucose is transported into body cells.
The uptake of glucose by liver, kidney and brain cells is by diffusion and does not require insulin.
Glucagon
The effects of glucagon are opposite to those of insulin.
