It is a large multi-branched polymer of glucose which is accumulated in response to insulin and broken down into glucose in response to glucagon. The pancreas produces insulin which allows the transport of glucose into the cell. This triggers your pancreas to produce glucagon. Insulin and glucagon are the hormones which make this happen. The Hypo Program is the world's first and only structured education program. Gluconeogenesis also occurs in the kidneys and some other organs. Insulin - Diabetes Like insulin, the target organ for glucagon is also the liver, though it stimulates the opposite process the breakdown of glycogen into glucose. Also, too much insulin and/or exercise without enough corresponding food intake in diabetics can result in low blood sugar (hypoglycemia). While high blood sugar levels are most commonly caused by an issue with not having enough insulin and not an isolated glucagon issue, its possible to have elevated blood sugar levels from rare glucagon issues.
