If it costs 11.0 kcal/mol to "run" the Na/K ATPase (i.e., pumping 3 Na* ions out of the cell and 2 K* ions into the cell per 1 ATP hydrolyzed), then what is the minimum concentration of ATP required to provide just enough energy to run the Na/KATPase? In other words, what does the concentration of ATP need to be so that the free energy of ATP hydrolysis is -11.0 kcal/mol. Assume that AG' is -7.3 kcal/mol, [P] is 3.5 mM, [ADP] is 0.9 mM, the pH is 7.2, and that the temperature is '37 °C. 5.0 mM 4.0 mM none of the other choices is correct (i.e., within 5% of the correct answer) 0.8 mM 1.3 mM
