Human blood contains 1.00 gram of glucose (C6H12O6)per liter, and the average person contains 5.20 L of blood. In metabolizing glucose, 17.1 MJ/kg of energy is released, of which 50.0% is lost as heat and 50.0% is used to make adenosine triphosphate (ATP).
a. How much energy could be stored in the ATP of the blood of an average person?
b. If the metabolic heat of the glucose is removed from the body by the evaporation of perspiration, how much perspiration is evaporated per gram of glucose metabolized? Assume the heat of vaporization of perspiration (H2O) is 40.6 MJ/kgmole.
