How many ATP molecules could maximally be generated from one molecule of glucose, if the complete oxidation of one mole of glucose to ${\mathrm{CO}}_2$ and ${\mathrm{H}}_2\mathrm{O}$ yields 686 kcal and the useful chemical energy available in the high energy phosphate bond of one mole of ATP is 12 Kcal?

When an electron is shifted to a more electronegative atom, its potential energy:

The number of molecules of carbon dioxide produced by three turns of the Krebs cycle would be:
