Question
Another hormone involved in the control of plasma glucose concentration is glucagon.
Explain how glucagon increases blood glucose concentration.
Solution
Glucagon is a hormone produced by the pancreas that works to raise the concentration of glucose and fatty acids in the bloodstream. It is part of a group of hormones that maintain glucose homeostasis, the others being insulin and somatostatin.
Here's how glucagon increases blood glucose concentration:
-
When blood glucose levels are low, the alpha cells in the pancreas release glucagon.
-
Glucagon travels to the liver, its primary target.
-
In the liver, glucagon promotes the conversion of stored glycogen into glucose. This process is known as glycogenolysis.
-
Glucagon also promotes the creation of new glucose molecules through a process called gluconeogenesis.
-
The newly formed glucose is released into the bloodstream, increasing blood glucose levels.
-
As blood glucose levels rise, the release of glucagon is inhibited, preventing blood glucose levels from becoming too high.
This process ensures that the body always has a steady supply of glucose for energy, even when you haven't eaten for a while.
