Aerobic Respiration (with oxygen again) Within two minutes of exercise, the body starts to supply working muscles with oxygen. When oxygen is present, aerobic respiration can take place to break down the glucose for ATP. This glucose can come from several places: remaining glucose supply in the muscle cells. glucose from food in the intestine.

Although you use energy as you climb, your body and the boulder also gain energy—potential energy. When the boulder is at the top of the hill, you can let it go so it rolls back down again. It can roll down because it has stored potential energy. In other words, it has the potential to roll down the hill all by itself.
