WebNADH molecules from glycolysis must travel into the mitochondria to pass their electrons to the electron transport chain. Because this process takes some energy, for every NADH from glycolysis, 2 ATP are formed, instead of 3. Add up all of the ATPs from each NADH and FADH, produced during the complete breakdown of one glucose molecule.
