    In which one of the following reactions, substrate level phosphorylation does not occur?

    A)  1, 3 bisphosphoglyceric acid \[\to \]3-phosphoglyceric acid

    B)  Glucose-6-phosphate \[\to \] Fructoses- phosphate

    C)  Succinyl Co-A \[\to \]Succinic acid

    D)  Phosphoenol pyruvic acid\[\to \]Pyruvic acid

    Correct Answer: B

    Solution :

                     Substrate level phosphorylation involve the direct transfer of a phosphate group from a substrate molecule to ADP for the formation of ATP.
