Aglucose molecule is completely broken down to carbon dioxide and water in glycolysis and the citric acid cycle, but together these two processes yield only a few molecules of atp. in which molecule(s) is most of the energy extracted from the complete oxidation of glucose stored? see concept 9.4 (page 174) a glucose molecule is completely broken down to carbon dioxide and water in glycolysis and the citric acid cycle, but together these two processes yield only a few molecules of atp. in which molecule(s) is most of the energy extracted from the complete oxidation of glucose stored? see concept 9.4 (page 174) it is stored in the atp that was formed by glycolysis and the citric acid cycle it is stored in nadh and fadh2 it is stored in pyruvate it is stored in the carbon dioxide and water molecules released by glycolysis and the citric acid cycle
