The metabolism of glucose, C6H12O6 (-12733 KJ/MOL), yields carbon dioxide, CO2 (g) (-393.5) , and water, H2O(1) (-285.8), as products. Energy released in the process is converted to useful work, w , with about 67.0% efficiency. Calculate the mass of glucose metabolized by a 79.7 kg person in climbing a mountain with an elevation gain of 1530m . Assume that the work performed in the climb is four times that required to simply lift 79.7kg by 1530m.
