In these scenarios, glucagon tells your liver and muscle cells to break down stored glycogen back into glucose. If the blood glucose level falls to dangerously low levels (as during very heavy exercise or lack of food for extended periods), the alpha cells of the pancreas release glucagon, a hormone which travels through the blood to the liver, where it binds to glucagon receptors on the surface of liver cells and stimulates them to break down glycogen stored inside the cells into glucose (this process is called glycogenolysis). 7. 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. In this article, we explain the functions and processes of insulin and glucagon, how they work as medications, and their effects on a persons blood sugar levels.

The picture on the left shows the intimate relationship both insulin and glucagon have to each other. Diabetes occurs when the pancreas does not produce enough insulin or when the body does not use insulin properly (called insulin resistance). Glycogenolysis occurs primarily in the liver and is stimulated by the hormones glucagon and epinephrine (adrenaline). Theres also a synthetic form of glucagon that can be administered as an injection or nasal powder (dry nasal spray). After a meal, increased plasma glucose promotes the release By storing glucose, the liver ensures the bodys blood glucose levels remain steady between meals and during sleep. Glycogen is a stored form of glucose. thus the Cori cycle is interrupted. 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.
