A cofactor tightly bound to the enzyme permanently is called:
Correct answer: B. Prosthetic group
- A. Activator
- B. Prosthetic group
- C. Coenzyme
- D. Apo-enzyme
Explanation
A prosthetic group is a non-polypeptide unit tightly and permanently bound to an enzyme, contributing to its function. It is a specific type of cofactor that remains attached to the enzyme. This close association is essential for the enzyme's activity.

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.
