During a 20-minute workout, a person burns 350 calories. What is the number of grams of glucose undergoing glycolysis in muscle cells with ample supply of oxygen? NADH in muscle cells is transported via the glycerol phosphate shuttle (which byhpasses Complexes I and II of the ETC). The human ATP synthase has 8 c subunits. Take note: Molar mass of glucose is 180 g/mol 1 calorie = 4.184 J phosphorylation potential in muscle cells is ~55 kJ/mol

Characterizing Glycolysis List the reactions of glycolysis that a. are energy consuming (under standard-stale conditions), b. are energy yielding (under standard-state conditions), c. consume ATP. d. yield ATP e. are strongly influenced by changes in concentration of substrate and product because of their molecularity. f. are at or near equilibrium in the erythrocyte (see Table 18.2).
A 70-kg adult human (154 lb) could meet his orher entire energy needs for one day by eating 3 moles ofglucose (540 g). (We do not recommend this.) Each mol-ecule of glucose generates 30 molecules of ATP when it isoxidized to CO2. The concentration of ATP is maintained incells at about 2 mM, and a 70-kg adult has about 25 litersof intracellular fluid. Given that the ATP concentrationremains constant in cells, calculate how many times perday, on average, each ATP molecule in the body is hydro-lyzed and resynthesized.
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.)
Intramitochondrial ATP concentrations are about 5 mM, and phosphate concentration is about 10 mM. Consider that ADP is five times more abundant than AMP. a. Calculate the molar concentrations of ADP and AMP at an energy charge of 0.85. b.

How many ATP molecules could maximally be generated from one molecule of glucose, if the complete oxidation of 1 mole of glucose to CO2 and H2O yields 686 kcal of free energy and the useful chemical energy available in the high- energy phosphate bond of 1 mole of ATP is 12 kcal?
Consider ten glucose molecules that enter a cell. How many ATP can be generated by the complete catabolism of these into CO2 and H2O?
