The metabolism of glucose is about 66% efficient, meaning that about 66% of the heat released during the breakdown of glucose is converted to useful work. A 70.0 kg hiker climbs up a rocky outcrop from an initial elevation of 1010 ft to a final elevation of 1634 ft. Calculate the mass of glucose (grams) metabolized during the hike. (Assume the actual work performed by the hiker is five times that required to lift 70.0 kg through an elevation from 1010 ft to 1634 ft. AHp of glucose = -1273.3 kJ/mol. Acceleration due to gravity is 9.8 m/s2).​
