Questions & Step-by-Step Solutions

What is the effect of glucagon on blood glucose levels?
  • Step 1: Understand that glucagon is a hormone produced by the pancreas.
  • Step 2: Know that glucagon's main job is to raise blood glucose levels.
  • Step 3: Learn that glucagon does this by signaling the liver to break down glycogen (stored glucose) into glucose, a process called glycogenolysis.
  • Step 4: Recognize that glucagon also helps the liver create new glucose from non-carbohydrate sources, a process called gluconeogenesis.
  • Step 5: Conclude that both glycogenolysis and gluconeogenesis lead to an increase in the amount of glucose in the blood.
