Read the following statements and choose the correct option: 1. Prosthetic groups are organic compounds that are tightly bound to the apoenzyme 2. Co-enzymes are organic compounds but their association with the apoenzyme is only transient, usually occuring during the course of catalysis 3. Co-enzymes serve as cofactors in a number of different enzyme catalysed reactions 4. Coenzyme nicotinamide adenine dinucleotide a

Step-by-step solution

Co-enzymes are also organic compounds but their 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, e.g., coenzyme nicotinamide adenine dinucleotide (NAD) and NADP contain the vitamin niacin.
