Use the following data to determine the maximum rate at which a standard man can climb a mountain: Blood contains 15.3 wt% hemoglobin (with molecular weight 65,000 g/mol). Each hemoglobin molecule can carry four oxygen molecules. The heart pumps 111 cm3/s blood of density 1.06 g/cm3. Each oxygen molecule can oxidize one sugar unit (the chemical formula per sugar unit is CH2O, which is an organic alcohol group) to CO2 and H2O; the oxidation of 1 g sugar yields about 17 kJ of energy, of which 25% can be used to do muscle work. (Assume the climber has a mass of 78 kg.)
