Question

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

• A. Two
• B. Thirty
• C. Fifty seven
• D. One

Answer 1

The correct option is C Fifty seven

Complete oxidation of one mole of glucose yields = 686 kcal.

Chemical energy available in high energy phosphate bonds of one mole of ATP = 12 kcal.

ATP molecules maximally generated from one molecule of glucose = 686/12 = 57 ATP molecules.
