Compound B, which is phosphoenolpyruvate, contains a high-energy bond between its phosphate group and its enol group. This high-energy bond allows the transfer of a phosphate group to ADP to form ATP via substrate-level phosphorylation. The other compounds in the diagram do not contain a high-energy bond.
