Cells use the hydrolysis of adenosine triphosphate (ATP) as a source of energy. The conversion of ATP to ADP has a standard free-energy change of -30.5 kJ>mol. If all the free energy from the metabolism of glucose, C6H12O61s2 + 6 O21g2 ¡ 6 CO21g2 + 6 H2O1l2 goes into the conversion of ADP to ATP, how many moles of ATP can be produced for each mole of glucose?
Given the following data:
2 C6H6(l) + 15 O2(g) → 12 CO2(g) + 6 H2O(l) ΔG0= -6399 kJ
C(s) + O2(g) → CO2(g) ΔG0= -394 kJ
H2(g) + ½O2(g) → H2O(l) ΔG0= -237 kJ
