Respiration in Plants Question 15
15. How many ATP molecules could maximally be generated from one molecule of glucose, if the complete oxidation of one mole of glucose to $CO_2$ and $H_2 O$ yields $686 kcal$ and the useful chemical energy available in the high energy phosphate bond of one mole of ATP is 12 kcal?

Answer : b
Hints & Solutions
(b) $12 kcal$ of energy present in one molecule of ATP & on oxidation of one mole of glucose into $CO_2$ and $H_2 O$ energy released is $686 kcal$. So no. of ATP which can store this energy would be $=57.1=57$ ATPs.
