Options
- A(A)-(II), (B)-(IV), (C)-(I), (D)-(III)
- B(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
- C(A)-(IV), (B)-(II), (C)-(I), (D)-(III)
- D(A)-(II), (B)-(IV), (C)-(III), (D)-(I)
Correct answer
A. (A)-(II), (B)-(IV), (C)-(I), (D)-(III)
Step-by-step solution
The protein portion of the enzyme is called the apoenzyme. Prosthetic groups are organic compounds that are tightly bound to the apoenzyme. Co-enzymes are organic compounds whose association with the apoenzyme is only transient, usually occurring during the course of catalysis. Metal ions form coordination bonds with side chains at the active site and at the same time form one or more coordination bonds with the substrate. Therefore, the correct match is (A)-(II), (B)-(IV), (C)-(I), (D)-(III). Answer: (A)-(II), (B)
