Which of the following best describes a coenzyme?
Correct answer: C. Loosely bonded non-protein part of an enzyme.
- A. Covalently bonded non-protein part of an enzyme.
- B. Cofactor consists of metal ions.
- C. Loosely bonded non-protein part of an enzyme.
- D. Both A and B.
Explanation
A coenzyme is a non-protein organic compound that associates with an enzyme to facilitate the enzyme's activity. Coenzymes are essential for the proper functioning of many enzymes, as they participate in catalysis by carrying chemical groups between different enzymes or from one part of a large enzyme molecule to another.

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.
