Which of the following best describes the prosthetic group?
Correct answer: C. Covalently bounded non-protein part of an enzyme
- A. Loosely bonded non-protein part of an enzyme
- B. Cofactor consists of metal ion
- C. Covalently bounded non-protein part of an enzyme
- D. None of these options are correct
Explanation
Covalently bounded non-protein part of the enzyme.A prosthetic group is a non-protein molecule that is covalently bound to an enzyme and is necessary for its proper function. Unlike a loosely bound non-protein part, a prosthetic group is tightly and permanently attached to the enzyme. It plays a crucial role in the enzyme's catalytic activity or structural stability.

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.
