What is the primary action of glucagon in the body?

Lower blood glucose levels
Promote protein synthesis
Raise blood glucose levels
Stimulate fat metabolism

The correct answer is: Raise blood glucose levels

The primary action of glucagon in the body is to raise blood glucose levels. Glucagon is a hormone produced by the alpha cells of the pancreas. When blood sugar levels drop, glucagon is released into the bloodstream and acts primarily on the liver. Its main functions include promoting glycogenolysis, which is the breakdown of glycogen into glucose, and gluconeogenesis, the process of generating glucose from non-carbohydrate sources. By increasing the availability of glucose in the blood, glucagon plays a crucial role in maintaining normal blood sugar levels, especially during fasting or in response to low blood glucose. This mechanism is essential for providing energy to the body, particularly for the brain and muscles, which rely heavily on glucose as a fuel source during times of need. Understanding glucagon's role highlights its importance in regulating blood sugar levels and ensuring proper metabolic balance in the body.
