Vedclass · Answer

(B) The Assertion is correct: $A$ cofactor can be a prosthetic group,which is an organic compound tightly bound to the apoenzyme (protein part).The Reason is also correct: $NAD$ (Nicotinamide Adenine Dinucleotide) is derived from the vitamin niacin (Vitamin $B_3$) and functions as a co-enzyme,which is a type of cofactor that binds transiently to the enzyme.However,the Reason does not explain why a cofactor can be a prosthetic group; they are two separate facts about enzyme cofactors. Therefore,both are correct,but the Reason is not the correct explanation of the Assertion.

$A$ : Cofactor of an enzyme may be a prosthetic group.
$R$ : $NAD$ derived from niacin is a co-enzyme.
