Digestive enzymes commonly catalyze hydrolysis reactions.

### Why this is right Hydrolases catalyze bond cleavage using water. Many digestive enzymes break food molecules into smaller products through hydrolysis. ### The concept Enzyme classes are often grouped by reaction type. Hydrolases add the elements of water across a bond during cleavage, while other classes transfer groups, rearrange atoms, or catalyze oxidation-reduction reactions. ### Terms - **Hydrolase**: an enzyme that catalyzes bond cleavage by water. - **Hydrolysis**: a reaction in which water participates in breaking a bond. ### Remember When a reaction uses water to split a bond, consider a hydrolase.
