Thin biological cells that have a plentiful supply of O2, glucose is oxidezed completely to CO2 and H20 by a process called aerobic oxidation. Musclells may be deprived of O2 during vigorois exercise and, in that case, one molecule of glucose is converted to two molecules of lactic acid (CH2CH(OH)COOH) by a process called anaerobic glycolysis.
(a) when 0.3212 g of glucose was burned in a bomb calorimenter of calorimeter constant 641J/K the temperature rose by 7.793K.
Calculate (i) The standard molar enthalpy of combustion (ii)the standard internal energy of combustion and (iii) the standard enthalpy of formation of glucose.
(b) What is the biological advantage (in KJ per mole of energy released as heat) of complete aerobic oxidation comparred with anerobic glycolysis to lactic acid?
