glycolysis/gluconeogenesis pathway glucose oxidation pathway glycolysis pathway Embden-Meyerhof-Parnas pathway Glycolysis PW:0000640 The glycolytic pathway converts the six-carbon glucose to two three-carbon pyruvate molecules. The ten reactions of glycolysis can be subdivided into an energy-consuming 'stage I' and an energy-generating 'stage II'. The net energy yield is two molecules of ATP. Pyruvate can be further oxidized via the citrate cycle, converted to lactose under anaerobic conditions or back to glucose via gluconeogenesis. glycolytic process pathway
