Options
- A(A)-(I), (B)-(II), (C)-(III), (D)-(IV)
- B(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
- C(A)-(II), (B)-(I), (C)-(III), (D)-(IV)
- D(A)-(I), (B)-(II), (C)-(IV), (D)-(III)
Correct answer
C. (A)-(II), (B)-(I), (C)-(III), (D)-(IV)
Step-by-step solution
Based on the classification of cofactors in enzymes: (A) Prosthetic groups are organic compounds that are distinguished from other cofactors in that they are tightly bound to the apoenzyme. Hence, (A) matches with (II). (B) Co-enzymes are also organic compounds but their association with the apoenzyme is only transient, usually occurring during the course of catalysis. Hence, (B) matches with (I). (C) Metal ions form coordination bonds with side chains at the active site and at the same time form one or more coordi
