Ask a question


A hormone secreted by the pancreas, glucagon plays a role in the transformation of glucides stored in the liver (glycogen) into glucose, which is released into the bloodstream. This process is called glycogenolysis. Causing a rise in blood sugar, the function of glucagon is called hyperglycemic. The coordination of insulin-- which plays the opposite role-- and of glucagon permits the correct blood sugar rate. Existing as a medication, this hormone is recommended in the treatment of severe hypoglycemia. It is administered through intravenous injections.
