What is the role of glucagon in glucose metabolism?

Step 1: Understand that glucagon is a hormone made by the pancreas.
Step 2: Know that glucagon is produced by special cells called alpha cells.
Step 3: Learn that the main job of glucagon is to raise blood sugar levels.
Step 4: Recognize that glucagon does this by two main processes: gluconeogenesis and glycogenolysis.
Step 5: Understand gluconeogenesis as the process of making new glucose from non-carbohydrate sources in the liver.
Step 6: Understand glycogenolysis as the process of breaking down glycogen (stored glucose) into glucose in the liver.
Step 7: Conclude that when glucagon is released, it helps to ensure that your body has enough glucose in the blood for energy.
