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 $C O_{2}$ and $H_{2} O$ yields $686 k c a l$ 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) $12 k c a l$ of energy present in one molecule of ATP & on oxidation of one mole of glucose into $C O_{2}$ and $H_{2} O$ energy released is $686 k c a l$ . So no. of ATP which can store this energy would be $= 57.1 = 57$ ATPs.
