Answer
Metabolism is the chemical reaction in the body's cells that change food into energy. Human bodies need this energy to do everything from moving to thinking to growing. Specific proteins in the body control the chemical reactions of metabolism.
Anabolism is the synthesis of complex molecules from simpler ones. These chemical reactions require energy.
Catabolism is the breakdown of complex molecules into simpler ones. These reactions release energy.
