Catabolism

Catabolism is a metabolic process that breaks down complex molecules into smaller ones to release energy. This process is the opposite of anabolism, which builds complex molecules from simpler ones using energy. Catabolism is an essential part of metabolism, as it provides the energy needed for various functions in the body, including muscle movement, cell division, and organ function.

Examples

An example of catabolism is the breakdown of glucose into pyruvate during glycolysis, which is a key step in cellular respiration. Another example is the breakdown of proteins into amino acids, which can then be used for energy or to synthesize new proteins.

Synonyms and Antonyms

Synonyms for catabolism include degradation, breakdown, and decomposition. Antonyms include anabolism, synthesis, and build-up.
