In TCA, substrate level phospherylation takes place in______________?
Correct answer: B. Succinyl CoA to Succinate
- A. Alpha ketoglutrate to succinyl CoA
- B. Succinyl CoA to Succinate
- C. Succinate to fumarate
- D. Oxalocetate to citrate
Explanation
Substrate-level phosphorylation in the TCA cycle occurs when succinyl-CoA is converted to succinate, producing GTP or ATP directly. The other listed steps do not form a high-energy phosphate product directly.
