If the enzyme for a particular step … WebFor every glucose molecule fully metabolized to CO2 and H2O, we receive 38 ATP. There are eight kcal of energy in every ATP high-energy phosphate bond. Hence the net recovery of energy is 38 × 8 = 304 kcal. The efficiency of converting glucose bond energy into ATP high-energy P bond is therefore 304/674 × 100 = 45%.
