Final answer:
Hydrolysis is the process of breaking down complex macromolecules into smaller molecules by splitting water molecules. Enzymes in the body catalyze hydrolysis reactions to break bonds and release energy for the absorption of nutrients by cells.
Step-by-step explanation:
Hydrolysis is the process of breaking down complex macromolecules into smaller molecules by splitting water molecules. It is catalyzed by specific enzymes in our body, such as amylase, sucrase, lactase, maltase, pepsin, peptidase, and lipases. Hydrolysis reactions break bonds and release energy, allowing for the absorption of nutrients by cells in the intestine. Therefore, the statement that any molecule that can be broken down into useful nutrients is broken down by hydrolysis is true.
