Quizplus · Accepted Answer

Enzymes are protein molecules that act as catalysts to speed up chemical reactions in the body. They are involved in the breakdown of complex molecules into simple ones (e.g. digestion) as well as building up complex molecules from simpler ones (e.g. protein synthesis). Enzymes are essential in the body, as they allow reactions to occur at a temperature compatible with life and at a rate that is compatible with the demands of the body.
