Verified step by step guidance1
Understand the role of digestive enzymes: Digestive enzymes are responsible for breaking down large macromolecules into smaller, absorbable units. This process typically involves the addition of water molecules to break chemical bonds.
Identify the type of reaction involved: The breakdown of macromolecules by digestive enzymes is a hydrolysis reaction, where water is used to cleave chemical bonds.
Match the reaction type to the enzyme class: Enzymes that catalyze hydrolysis reactions are classified as hydrolases. These enzymes facilitate the addition of water to break bonds, which is characteristic of digestive processes.
Review the options provided: Ligase enzymes join two molecules together, lyase enzymes break bonds without water, and transferase enzymes transfer functional groups between molecules. None of these match the hydrolysis reaction characteristic of digestive enzymes.
Conclude that the correct class of enzyme for digestive enzymes is hydrolase, as they catalyze the hydrolysis of macromolecules.
