Question
The essential chemical components of many coenzymes are
proteins
nuclei acids
carbohydrates
vitamins
Solution
D.
vitamins
Coenzymes are organic molecules that are required by certain enzymes to carry out catalysis. They bind to the active site of the enzyme and participate in catalysis but are not considered substrates of the reaction. Essential chemical components of many coenzymes are vitamins eg, coenzyme Nicotinamide Adenine Dinucleotide (NAD) and NADP contain the vitamin niacin. Proteins, nucleic acids and carbohydrates are not enzymatic biomolecules.
