Ribose is a monosaccharide constituent of many:
Correct answer: B. Coenzymes
- A. Enzymes
- B. Coenzymes
- C. Vitamins
- D. All of these
Explanation
The correct answer is coenzymes. Ribose is a crucial component of coenzymes such as NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide). These coenzymes are essential for various biochemical reactions in the body, including energy production. The other options are incorrect because enzymes are primarily protein-based, and vitamins do not typically contain ribose.
