The process in which complex substances in the body are broken down into simpler ones, usually releasing energy in the process.
During catabolism, the body breaks down food into energy that can be used for various functions.
Catabolism is formed from "cata-" (from Greek "kata", meaning down) and "ballein" (meaning to throw). The word describes the process of breaking down complex molecules into simpler ones, essentially 'throwing down' or breaking down substances in the body.
Think of 'down' ('cata-') as breaking things apart, which helps you remember that catabolism refers to the process of breaking down complex substances.
