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. what happened to most of the energy that the cell obtains from the oxidation of glucose? view available hint(s) 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. what happened to most of the energy that the cell obtains from the oxidation of glucose? it is stored in the carbon dioxide and water molecules released by these processes. 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 was lost as heat.
