Step 1: Understanding the Concept:
Coenzymes are organic molecules required for enzyme activity.
They are derived from vitamins.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the sources of coenzymes.
Step 3: Detailed Explanation:
Coenzymes are derived from water-soluble vitamins.
Examples:
- NAD\(^+\)/NADP\(^+\) from niacin (B3).
- FAD from riboflavin (B2).
- CoA from pantothenic acid (B5).
Fat-soluble vitamins are not coenzymes.
Thus, coenzymes are converted forms of water-soluble vitamins.
Step 4: Final Answer:
Coenzymes are converted forms of water-soluble vitamins.
Hence, the correct option is (B).
