Item EB082001: To maintain a stable amount of glucose in the blood during exercise the body breaks down glycogen molecules into glucose molecules.
If the amount of glucose in a person’s blood were to drop too low during exercise, the person’s brain would not function properly and the person could faint. How does the person’s body maintain a stable amount of glucose in the blood during exercise?
- The body speeds up the reaction during which glucose and oxygen react to form carbon dioxide and water.
- The body makes glycogen molecules and water molecules from glucose molecules.
