Enzymes speed up all of the reactions that happen inside cells. They help with digestion and our metabolism. Enzymes can do a few different things like:
Break up big molecules into smaller pieces, so they can be absorbed more easily by the body.
Enzymes also are very picky catalysts, and will only “speed up” certain types of reactions.
Hope this helps you!! (:
