Question

Prosthetic groups differ from co-factors in that the former is (A) tightly bound to the coenzyme (B) tightly bound to the apoenzyme (C) loosely bound to the inorganic catalyst (D) tightly bound to the active site

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 the enzyme to make the enzyme catalytically active. In these instances, the protein portion of the enzymes is called the apoenzyme. Three kinds of cofactors may be identified: prosthetic groups, co-enzymes and metal ions.
