ADP + phosphoenolpyruvate + CO2 the enzyme may function in the conversion of carbon skeletons to phosphoenolpyruvate, which, depending on the energy requirements of the phloem, is subsequently utilised by either gluconoeogenesis or the Krebs cycle, which both consume protons Cucumis sativus ATP + oxaloacetate
