To survive in an acidic environment, the cells utilize the energy of ATP hydrolysis to pump out 2 protons against its electrochemical potential. Calculate the minimum level of cellular ATP (in unit of uM) necessary for this operation. The cellular concentrations of ADP and Pi are constant at 38 uM and 120 uM, respectively. The pH inside the cell is 7, and the cell is placed in a culture solution having a pH of 5.8. The standard free energy of ATP hydrolysis is -31.3 kJ at 37oC (Biochemistry standard state). The membrane potential is -0.07 V.

What is an example of a physical property?

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback
