Do you know any step in the TCA cycle where there is substrate level phosphorylation. Which one?
There is one stage in the citrus cycle where there is substrate-level Phosphorylation. It is the one where succinic acid is produced from succinyl CoA. So, it leads to a conversion of the GDP (Guanosine diphosphate) molecule to the GTP (Guanosine Triphosphate) molecule.
