Use the following data to determine the maximum rate at which a
standard man can climb a mountain: Blood contains 15.0 wt%
hemoglobin (with molecular weight 65,000 g/mol). Each hemoglobin
molecule can carry four oxygen molecules. The heart pumps 106
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 72 kg.)
