Question

How many ATP molecules could maximally be generated from one molecule of glucose, if the complete oxidation of one more of glucose to $C{O}_2$ and $H_{2}O$ yields $686$ kcal and the useful chemical energy available in the high?

Answer 1

Each ATP molecule on hydrolysis releases 7.3 Kcal of energy. Hence, number of ATP molecules that can be generated by 686 Kcal will be 686/7.3 = 94 ATP molecules.
