You need energy to maintain your body functions----heart beating, body temperature, breathing, thinking etc. Things your body does that you do not realize it is doing. Metabolism: • A process by which your body breaks down food to release energy. When your body uses the nutrients in foods, a series of chemical reactions occur inside your cells and energy is released. • This energy is also used for the growth and repair of the body.
