Consider the following statements: ( A ) Coenzyme or metal ion that is tightly bound to enzyme protein is called prosthetic group. ( B ) A complete catalytic active enzyme with its bound prosthetic group is called apoenzyme. Select the correct option.

Step-by-step solution

Many enzymes show catalytic activity only in association with certain non-protein substances. Those substances are known as cofactors (cofactors may be simple metal ions, e.g. Mg ++ or K + etc.). The enzymes which works only in presence of cofactors are called apoenzymes . An organic non-protein cofactor which is easily separable from the apoenzyme is called coenzyme, and the non-protein organic cofactor that is tightly bound to and non-dissociable from the enzyme is termed as prosthetic group , e.g. biotin of carb
