What function does insulin serve for the body?
  1. Raises blood glucose levels in the body
  2. Transforms food into glucose
  3. Regulates energy and glucose metabolism throughout the body
  4. Stimulates hormone production
Explanation
Answer - C - Insulin regulates energy and glucose metabolism throughout the body. After a meal, glucose enters the bloodstream, which causes a rise in blood glucose levels. The increased levels of glucose cause the release of insulin, which then causes the cells in liver, muscle, and fat tissue to take up the glucose and store it as glycogen.
