IPA: //ˈhoʊloʊˌɛnzaɪm//
KK: /ˈhoʊloʊˌɛnzaɪm/
A complete and active enzyme that is made up of a protein part and a non-protein part, which is necessary for its function.
The holoenzyme is essential for the biochemical reactions in the cell.
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.
Think of 'whole' ('holos') to remember that a 'holoenzyme' is the complete form of an enzyme that is fully active.
