Question

How many ATP molecules could maximally be generated from one mole of glucose, if the complete oxidation of one mole of glucose to $C{O}_2$ and $H_{2}O$ yields 686 kcal and the useful chemical energy in a phosphate bond of one mole of ATP is 12 kcal?

• A. 1
• B. 2
• C. 30
• D. 57

Answer 1

The correct option is D 57

1ATP = 12 K cal.
? = 686 K. cal. $\frac{686}{12}=57.16$

Therefore the amount of ATP produced per mole of glucose is 57.16 moles.
