| − | '''Glucagon''' is an [[endocrine]] [[hormone]] which acts to raise the level of [[glucose]] in the bloodstream. Glucagon is produced by the [[alpha cells]] of the pancreas, where it is stored until [[hypoglycemia]] occurs. It has an effect opposite that of [[insulin]], which acts to reduce blood glucose levels.

| − | In the liver, glucagon stimulates the breakdown of [[glycogen]] into [[glucose]], which is then released into the bloodstream. A similar reaction occurs in muscle tissue, although the glucose produced there is used by the muscle and not released. [[Glycogenolysis]] can maintain blood glucose levels for several hours, until the glycogen stores are depleted.

| − | In the longer term, glucagon also stimulates [[gluconeogenesis]] in the liver and kidneys; a process in which new glucose molecules are created from chemicals released by the breakdown of protein and fat. Thus the body can maintain blood glucose levels over a period of days to weeks at the expense of muscle and fat stores.

| − | Glucagon facilitates [[gluconeogenesis]] by directly stimulating [[lipolysis]], the breakdown of stored fats into [[free fatty acids]] which are needed for the production of new glucose molecules.
