A major source of energy in aerobic organisms is the combustion of glucose:
C6H12O6 + 6 O2 ® 6 CO2 + 6 H2O
DH°´ = -2816 kJ/molDS°´ = +181 J/°mol
(a) At 37°C, what is the value of DG°´ for this reaction?
(b) If during aerobic metabolism of 1 mole of glucose, 38 moles of ATP are produced from ADP, and the DG°´ for hydrolysis of ATP to ADP is -31 kJ/mol, what is the overall DG°´ for the combustion of glucose coupled to ATP formation?
(c) What is the efficiency of the process in terms of the percentage of available free energy change captured in ATP?
