Vedclass · Answer

(D) Enzymes are composed of one or several polypeptide chains. However,there are a number of cases in which non-protein constituents called cofactors are bound to the apoenzyme to make the enzyme catalytically active.Cofactors are non-protein parts that are smaller in size compared to the protein part (apoenzyme).Cofactors are of three kinds: prosthetic groups,coenzymes,and metal ions.Coenzymes are also organic compounds but their association with the apoenzyme is only transient,usually occurring during the course of catalysis.Since both cofactors (as a general term) and coenzymes (as a specific type of cofactor) are non-proteinaceous and smaller than the apoenzyme,both are correct in this context.
