Final answer:
Glucagon increases blood glucose levels by stimulating the liver to release stored glucose and convert amino acids into glucose.
Step-by-step explanation:
Glucagon is a hormone produced by the pancreas that helps increase blood glucose levels. When blood sugar levels drop, glucagon is released into the bloodstream. It signals the liver to break down glycogen (stored glucose) into glucose, which is then released into the blood. Glucagon also stimulates the liver to convert amino acids into glucose in a process called gluconeogenesis. These actions of glucagon help to raise blood glucose levels to maintain normal levels in the body.
