The essential chemical components of many coenzymes are vitamins. Which of the following vitamins is contained in the coenzymes Nicotinamide adenine dinucleotide (NAD) and NADP?

Step-by-step solution

Co-enzymes are organic compounds whose association with the apoenzyme is only transient, usually occurring during the course of catalysis. Furthermore, co-enzymes serve as co-factors in a number of different enzyme catalyzed reactions. The essential chemical components of many coenzymes are vitamins. As per NCERT, the coenzymes Nicotinamide adenine dinucleotide (NAD) and NADP contain the vitamin niacin. Riboflavin, thiamine, and ascorbic acid are incorrect as they are not the specific vitamin components of NAD and
