NEET Botany TCA Cycle MCQ Question
Which of the following statements about the TCA cycle is correct?
Succinyl-CoA is oxidised to oxaloacetic acid, allowing the TCA cycle to continue.
NADH is produced in the TCA cycle only during the conversion of succinyl-CoA.
GTP synthesis occurs through oxidative phosphorylation in the mitochondrial matrix.
Acetyl CoA is not required for the continuation of the TCA cycle.
Correct Answer
Detailed Explanation
Statement A is correct as succinyl-CoA is oxidised to oxaloacetic acid, which is essential for the TCA cycle to continue. Statement B is false because NADH is produced at multiple points in the cycle. Statement C is incorrect as GTP synthesis is a substrate-level phosphorylation, not oxidative phosphorylation. Statement D is incorrect since acetyl CoA is crucial for the cycle to initiate.
