MICROANATOMY

Detailed explanation-1: -Glycogen is a stored form of glucose (sugar). Your body primarily stores glycogen in your liver and muscles. Glucagon is a hormone that triggers liver glycogen to convert back into glucose and to enter your bloodstream so that your body can use it for energy.

Detailed explanation-2: -Insulin is a peptide hormone secreted by the cells of the pancreatic islets of Langerhans and maintains normal blood glucose levels by facilitating cellular glucose uptake, regulating carbohydrate, lipid and protein metabolism and promoting cell division and growth through its mitogenic effects.

Detailed explanation-3: -Insulin is a peptide hormone made in the beta cells of the pancreas that is central to regulating carbohydrate metabolism in the body (Wikipedia, 2016). After a meal, insulin is secreted into the bloodstream.

Detailed explanation-4: -Insulin is a storage hormone that promotes fat production and prevents fat from being broken down. In the liver, insulin allows for glucose to be made into glycogen. Glycogen is stored glucose that is broken down when the body needs energy.

Detailed explanation-5: -Through its various hormones, particularly glucagon and insulin, the pancreas maintains blood glucose levels within a very narrow range of 4–6 mM. This preservation is accomplished by the opposing and balanced actions of glucagon and insulin, referred to as glucose homeostasis.
