The chemical reactions involved
in cellular metabolism release energy because of the breakdown of nutrients.
Molecules are built to store energy. As cells divide, they use energy to copy
their genetic material. They build proteins from amino acids. Enzymes are proteins required for
cellular metabolism and to control metabolic reactions. Nutrients in body cells
are used for biochemical reactions that collectively are described as metabolism, during which time
sub-stances are built up and broken down continuously.
