Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1--3: Analysis
Statement A is false: GAPDH converts GAP into 1,3-BPG (not the reverse). Statement B is true. Statement C is true. Statement D is false: Pyruvate kinase (not isomerase) converts PEP to pyruvate.
Step 4: Conclusion
Only B and C describe correct enzyme-substrate relationships.
Final Answer: (D)
