A cofactor tightly bound to the enzyme on the permanent basis is called:
Correct answer: C. Prosthetic group
- A. Activator
- B. Coenzyme
- C. Prosthetic group
- D. Apo-enzyme
Explanation
The detachable cofactor is known as an activator if it is an inorganic ion. If the non-protein part is covalently bonded, it is known as a prosthetic group. If it is loosely attached to the protein part, it is known as coenzyme. An enzyme with its cofactor removed is called apoenzyme.

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.
