Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Co-enzymes are distinguished from prosthetic groups based on the nature of their association with the apoenzyme. Reason (R): Co-enzymes are tightly bound organic compounds, whereas prosthetic groups associate only transiently during catalysis. In the light of the above statements, choose the most a
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- C(A) is correct but (R) is not correct
- D(A) is not correct but (R) is correct
Correct answer
C. (A) is correct but (R) is not correct
Step-by-step solution
Assertion (A) is correct because both co-enzymes and prosthetic groups are organic compounds, but they are distinguished by how they bind to the apoenzyme. Reason (R) is incorrect because prosthetic groups are tightly bound to the apoenzyme, whereas co-enzymes associate only transiently, usually occurring during the course of catalysis. Answer: (A) is correct but (R) is not correct
