Vedclass · Answer

(D) Prosthetic groups are tightly bound organic or inorganic cofactors required for the catalytic activity of enzymes.$Mg^{2+}$ acts as a cofactor for many enzymes like hexokinase and $DNA$ polymerase.$Cu^{2+}$ is a prosthetic group in enzymes like cytochrome c oxidase.$Zn^{2+}$ is a prosthetic group in enzymes like carbonic anhydrase and carboxypeptidase.$Ag^{+}$ (silver ion) is a heavy metal ion that is not a naturally occurring prosthetic group in any known biological enzyme; in fact,it often acts as an enzyme inhibitor by binding to sulfhydryl groups.Therefore,the correct option is $D$.

Which one of the following metallic ions does not occur as a prosthetic group in any enzyme?
