MICROANATOMY

Detailed explanation-1: -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: -Glucagon secreted from pancreatic alpha cells in the islet of Langerhans plays an important role in maintaining glucose homeostasis by stimulating hepatic glucose production (1). Thus, in contrast to the glucose-depositing nature of insulin action, glucagon acts as a glucose-mobilizing hormone.

Detailed explanation-3: -’Alpha cells’ in the islets of Langerhans produce another important hormone, glucagon. This has the opposite effect to insulin, by helping release energy into the bloodstream from where it is stored, thus raising blood sugar levels.

Detailed explanation-4: -Function of liver glycogen stores Glucagon, in part, triggers glycogen in your liver to convert back to glucose so it can enter your bloodstream. This process is called glycogenolysis.

Detailed explanation-5: -Insulin is a hormone secreted by the pancreas that lowers blood glucose level by promoting the uptake of glucose by cells and the conversion of glucose to glycogen by the liver and skeletal muscle.
