= The membrane potential of a muscle cell is = - 90 mV. How much work does a sodium-potassium exchange pump in a muscle cell do during one cycle? How does this compare to the = 60 kJ/mol of energy released by the hydrolysis of ATP? Assume that work is done only to move ions across the membrane and that no work is required for conformational changes in the membrane proteins that form the pumps. The charge on an electron is= 1.6 X 10-19 C. Show all your work.
