the general term is cofactor, but more specifically, if the cofactor is an organic molecule, it is called a coenzyme.
Cofactors can be subdivided into either one or more inorganic ions, or a complex organic or metalloorganic molecule called a coenzyme; most of which are derived from vitamins and from required organic nutrients in small amounts. A cofactor that is tightly or even covalently bound is termed a prosthetic group.
