How many ATP molecules could maximally be generated from one molecule of glucose, if the complete oxidation of one mole of glucose to CO₂ and H₂O yields 686 kcal and the useful chemical energy available in the high energy phosphate bond of one mole of ATP is 12 kcal ?

[Solution from source] If all 686 kcal could be stored in ATP at 12 kcal per ATP, the maximum would be 686 / 12 ≈ 57 ATP. Thirty is close to the real yield from respiration, but the question asks for the theoretical maximum from the numbers given. Answer (3).
