In aerobic respiration, 36 or 38 molecules of ATP per molecule of glucose, depending on how many are gained through the electron transfer system.
The actual usable energy obtainable from the 38 ATP molecules that may be produced from this glucose is 288,800 calories (38 x 7,600 calories per ATP). Therefore, the complete oxidation of glucose is only about 40% efficient (288/686). The other 60% goes off as heat.
