If the non-protien part is loosely attached to the protein part in the enzyme, it is known as _.
Correct answer: A. Coenzyme
- A. Coenzyme
- B. Prosthetic group
- C. Cofactor
- D. Apoenzyme
Explanation
Prosthetic groups are compounds bound to enzymes by a covalent bond and their change from one form to another and back takes place in a single catalytic cycle. Coenzymes are organic molecules and quite often bind loosely to the active site of an enzyme. The term cofactors unite coenzymes and prosthetic groups. The meaning of apoenzyme is a protein that forms an active enzyme system by combination with a coenzyme.

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.
