How many ATP molecules could maximally be generated from one molecule of glucose, if the complete oxidation of one mole of glucose to $\mathrm{CO}_2$ and $\mathrm{H}_2 \mathrm{O}$ yields $686 \mathrm{kcal}$ and the useful chemical energy available in the high energy phosphate bond of one mole of ATP is $12 \mathrm{kcal}$ ?

Solution
Complete oxidation of one mole of glucose yields $=686 \mathrm{kcal}$.
Chemical energy available in high energy phosphate bonds of one mole of $\mathrm{ATP}=12$ ATP
ATP molecules maximally generated from one molecule of glucose $=$ $686 / 12=57$ ATP molecules.
