Root Explanation

Holoenzyme → It is formed from "holos" (from Greek, meaning whole or entire) and "enzyme" (from Greek "enzymon", meaning leaven or ferment). The term "holoenzyme" refers to the complete, active form of an enzyme that includes its cofactor, thus being the whole enzyme necessary for activity.

Memory Tip

Think of 'whole' ('holos') to remember that a 'holoenzyme' is the complete form of an enzyme that is fully active.
