Question

Are enzymes used to speed up reactions that build molecules, break molecules down, or both?

Answer 1

Enzymes are used to speed up reactions. They’re also called catalysts and their main purpose is as a speed boost for reactions

Answer 2

Answer: Enzymes deals with both .

An enzyme basically acts on a chemical reaction by speeding up the process.

A chemical reaction is either anabolic(synthesis by building up of smaller substances) or catabolic (breaking down of larger/bigger substances). Therefore an enzyme can speed up reactions to build up and break down molecules.
