Summary Introduction
To calculate:
The number of calories produced per day in the form of ATP by a resting individual.
Introduction:
ATP is also known as Adenosine triphosphate. It is a molecule which stores energy within cells and is the chief energy currency of the cell. It is the final product of the processes of photophosphorylation,

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.)
If the DGo for ATP hydrolysis into ADP + inorganic phosphate is -7.3 kcal/mole, and the DGo for sucrose synthesis from glucose + fructose is +5.5 kcal/mole, calculate standard free energy change for the combined reaction of ATP + glucose + fructose g ADP + sucrose + inorganic phosphate.
DGo = -12.8 kcal/mole
DGo = -1.8 kcal/mole
DGo = 0 kcal/mole
DGo = +1.8 kcal/mole
DGo = +12.8 kcal/mole

What is the role of glycogen metabolism (glycogenesis and glycogenolysis) and glycolysis in carbohydrate loading? Why is this practice more productive than usual without carbohydrate loading?arrow_forwardThe conversion of lactate to glucose in the liver requires the input of 6 mol of ATP for every mol of glucose produced. 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_forward
