Correct answer: C. Vitamin C
- A. Vitamin B
- B. Vitamin B2
- C. Vitamin C
- D. Vitamin B1
Explanation
Coenzymes are organic molecules that help in the catalysis of chemical reactions by binding to the active sites. Examples include NAD (nicotinamide adenine dinucleotide), NADP (nicotinamide adenine dinucleotide phosphate), and FAD (flavin adenine dinucleotide), and Vitamins B1, B2, B3. Vitamin C is not a coenzyme.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
