Its primary goal is to ensure a constant supply of energy to the brain and red blood cells, which rely heavily on glucose. Mechanisms of Action Glucagon initiates a process known as glycogenolysis, where it stimulates the liver to break down stored glycogen back into glucose, which is then released into the bloodstream.
How Glucagon Triggers Liver Glycogen Release for Blood Sugar Balance
Insulin and glucagon are two foundational hormones that orchestrate the intricate balance of blood glucose, ensuring your body’s cells receive a steady supply of energy. This hormone is released when the body senses a drop in blood glucose, such as during fasting, intense exercise, or between meals.
They operate on a seesaw mechanism, constantly adjusting to the body’s immediate needs to maintain euglycemia—normal blood glucose levels. This hormonal interplay ensures that blood sugar remains within a narrow, optimal range regardless of external food intake.
How Glucagon Triggers Liver Glycogen Release for Blood Sugar Balance
The Counterbalance: Glucagon's Role Glucagon, secreted by the alpha cells of the pancreas, serves as the counterbalance to insulin. Simultaneously, insulin signals the liver to absorb glucose and convert it into glycogen, a storage form of carbohydrate.
