An activated enzyme consisting of a polypeptide chain and a cofactor is called?
Correct answer: B. Holoenzyme
- A. Apoenzyme
- B. Holoenzyme
- C. Conjugated enzyme
- D. Hybrid enzyme
Explanation
Enzymes are proteins comprised of amino acids linked together in one or more polypeptide chains. Apoenzyme is a protein part that binds to a non-protein cofactor to form an active conjugated enzyme known as the holoenzyme. The cofactor and apoenzyme complex is called a holoenzyme.

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.
