I believe the answer is catabolism. Catabolism is the chemical breakdown of complex molecules into simpler molecules including hydrolysis of macromolecules into monomers. The catabolic reactions releases energy when bonds are broken and mainly involve oxidation reactions. Example of a catabolic reaction is glycolysis

Chemical digestion reduces large complex molecules to simpler compounds by the process of catabolism. Catabolism is the set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy, or used in other anabolic reactions.
