What is metabolism and how does it work? Metabolism consists of hormones and enzymes that convert food into fuel and also effects how efficiently the body burns that fuel. The fuel is converted into energy for the body to do anything from thinking to exercising.

According to KidsHealth.org there are two kinds of metabolism that occur at the same time. One is anabolism (constructive metabolism), which consists of building and storing while it supports the growth of new cells, maintenance of body tissues, and the storage of energy for future use. The second is catabolism (destructive metabolism), which is the process of producing the energy required for all activity in the cells. The cells break down large molecules to release energy which provides fuel for anabolism, heats the body, and allows the muscles to contract and the body to move.
