Root Explanation

Coenzyme is formed from "co-" (meaning together) and "enzyme" (from Greek "enzymon", meaning leaven or ferment). The word refers to a substance that works together with an enzyme to enhance its activity.

Memory Tip

Think of 'working together' ('co-') with a 'ferment' ('enzyme') to help a process — that's what a coenzyme does.
