It gets activated by the addition of an inorganic or organic Cofactor. The holoenzyme is known as an apoenzyme in combination with the Cofactor.
A Cofactor is known as a non-protein part consisting of the enzymes, which can be an organic chemical or metal ions. The cofactors which are organic chemicals are known as Coenzyme. These are loosely attached to the apoenzyme. The tightly bound Coenzymes are known as the prosthetic group.
