Question

what is the breaking of macromolecules by adding water called?
o dehydration synthesis
hydrolysis
catalysts

Explanation:

Hydrolysis is a chemical reaction where water is used to break down macromolecules. Catalysts are substances that speed up reactions but are not consumed. Dehydration synthesis is the opposite of hydrolysis, where water is removed to form bonds. So the process of breaking macromolecules by adding water is hydrolysis.

Answer:

hydrolysis
