Chapter 23, Problem 12P
Understanding Human Energy Consumption During Exercise Energy production in animals is related to oxygen consumption. The ruby-throated hummingbird consumes about 250 mL of oxygen per hour during its migration across the Gulf of Mexico. Use this number and the data in problem 11 to determine a conversion factor for energy expended per liter of oxygen consumed. If a human being consumes 12.7 kcal/min while running 8-minute miles, how long could a human run on the energy that the hummingbird consumes in its trans-Gulf flight? How many 8-minute miles would a person have to run to lose 1 pound of body fat?

Walking consumes approximately 100 kcal/mi. In the hydrolysis of ATP (ATP → ADP + Pi), the reaction that drives muscle contraction, ΔG°′ is −7.3 kcal/mol (−30.5 kJ/mol). Calculate how many grams of ATP must be produced to walk a mile. ATP synthesis is coupled to the oxidation of glucose (ΔG°′ = −686 kcal/mol). How many grams of glucose are actually metabolized to produce this amount of ATP? (Assume that only glucose oxidation is used to generate ATP and that 40% of the energy generated from this process is used to phosphorylate ADP. The gram molecular weight of glucose is 180 g and that of ATP is 507 g.)
According to as shown, cycling at 15 km/h requires less metabolic energy than running at 15 km/h. Suggest reasons why this is the case.

- Assume that the complete combustion of one mole of glucose to carbon dioxide and water liberates 2870 kJ/mol (AGo' = -2870 kJ/mol). If one contraction cycle in muscle requires 67 kJ, and the energy from the combustion of glucose is converted with an efficiency of 35% to contraction, how many contraction cycles could theoretically be fueled by the complete combustion of one mole of glucose?

Assume that the cellular concentrations of creatine phosphate, creatine, and phosphate are 21.6 mM, 2.16x10-3 mm, and 3.80 mM, respectively.

Investigators can monitor the extent of this process in a rat liver preparation by administering [¹4C]lactate and measuring the amount of [¹4C]glucose produced. Because the stoichiometry of O, consumption and ATP production is known (about 5 ATP per O₂), investigators can predict the extra O₂ consumption above the normal rate after administering a given amount of lactate. However, when they actually measure the extra O₂ used in the synthesis of glucose from lactate, it is always higher than what the stoichiometric relationships predict. What could explain this observation? Unproductive cycling of ADP and ATP occurs, with extra O, consumption. The initial production of lactate requires extra O₂. The conversion of [C]lactate to [C]glucose requires less ATP and less O₂. The production of [C]glucose uses more O, than the production of unlabeled glucose.arrow_forwardExplain the difference between ΔG°’ and ΔG and calculate the free energy (delta G) of hydrolysis of ATP in a rat liver cell in which the ATP, ADP, and Pi concentrations are 3.4, 1.3, and 4.8 mM.arrow_forward
