Question: substrate level phosphorylation in tca cycle is in step?
Answer: 6: The Citric Acid Cycle, Step 5. CoA is removed from succinyl-CoA to produce succinate. The energy released is used to make guanosine triphosphate (GTP) from guanosine diphosphate (GDP) and Pi by substrate-level phosphorylation. GTP can then be used to make ATP.
