Question:
Which vitamin is a precursor for the coenzyme NAD+?
Which vitamin is a precursor for the coenzyme NAD+?
Show Hint
Niacin (Vitamin B3) is directly involved in the production of NAD+, which plays a vital role in cellular metabolism.
Updated On: Jun 18, 2025
- Vitamin B1 (Thiamine)
- Vitamin B2 (Riboflavin)
- Vitamin B3 (Niacin)
- Vitamin B6 (Pyridoxine)
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Vitamin B3 (Niacin) is a precursor for NAD+ (Nicotinamide adenine dinucleotide), a coenzyme involved in redox reactions in cellular metabolism. Vitamin B1, B2, and B6 are important for other metabolic pathways but are not directly involved in the synthesis of NAD+.
