Coenzymes are derived from:
Correct answer: D. Vitamins
- A. Proteins
- B. Metal ions
- C. Carbohydrates
- D. Vitamins
Explanation
Coenzymes play a vital role in the function of enzymes, acting as carriers for chemical groups or electrons during biochemical reactions. They are predominantly derived from vitamins, making vitamins essential for proper metabolic processes. This is why Option D, Vitamins, is the correct answer.Option A, Proteins, is incorrect because while enzymes are often proteinaceous, coenzymes are non-protein organic molecules. Option B, Metal ions, is incorrect as metal ions serve as cofactors but are not organic and are not derived from vitamins. Option C, Carbohydrates, is incorrect since coenzymes are not typically derived from carbohydrates, but from vitamins.

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.
