The role of glucagon in high school

Glucagon's main role is to promote the decomposition of liver glycogen and non-sugar substances into glucose, thereby increasing blood sugar

levels.1. Promote liver glycogen decomposition

When blood sugar concentration decreases, glucagon binds to receptors on the surface of liver cells and activates a series of signaling pathways to promote liver glycogen decomposition into glucose, which is released into the blood to supplement blood sugar. This process can quickly provide energy to maintain the normal function of the body in a low glucose

state.2. Promote the conversion of non-sugar substances to glucoseGlucagon

can stimulate the liver and kidneys and other organs to convert some non-sugar substances, such as amino acids, glycerol, etc., into glucose, which helps to increase the source of blood sugar when hunger or energy demand increases, ensuring the body's energy supply.

In this way, glucagon plays an important role in maintaining blood sugar homeostasis, especially in stress or prolonged fasting, ensuring that organs such as the brain that rely on glucose for energy can function normally. At the same time, glucagon and insulin coordinate with each other to jointly regulate blood sugar levels to maintain the metabolic balance of the body.
