Answer:
Hydrolysis
Explanation:
Hydrolysis is a reaction that needs water to breakdown macromolecules into simpler units. 
Macromolecules are giant polymers made up of several repeating monomeric units. 
- These units are too complex for the body to digest and derive nutritional benefits from them. 
- During hydrolysis, the complex is broken down into monomers. 
- The monomeric units are absorbable and useful for the body.
