Metabolism意思

Metabolism refers to the chemical processes that occur within a living organism in order to maintain life. It involves the conversion of food into energy that the body can use, as well as the synthesis of complex molecules from simpler ones, and the breakdown of complex molecules into simpler ones. Metabolism can be divided into two main categories: catabolism, which is the breaking down of complex molecules into simpler ones, and anabolism, which is the synthesis of complex molecules from simpler ones.
