Correct answer: D. Holoenzyme
- A. Substrate
- B. Coenzyme
- C. Apoenzyme
- D. Holoenzyme
Explanation
An activated enzyme made of a polypeptide chain and a cofactor is called a holoenzyme. A holoenzyme is a functional enzyme that is composed of both a protein component (the apoenzyme or apoprotein), which is made up of one or more polypeptide chains, and a non-protein component known as a cofactor.

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.
