An enzyme without its cofactor is called:
Correct answer: B. Apoenzyme
- A. Coenzyme
- B. Apoenzyme
- C. Holoenzyme
- D. Proenzyme
Explanation
An enzyme without its cofactor is often referred to as the "apoenzyme." The apoenzyme is the protein component of an enzyme that lacks the necessary cofactor or coenzyme for its full catalytic activity. The cofactor is a non-protein component that is essential for the enzyme to function optimally.

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.
