Hi; Could somebody please help me with the following question: During the action potential, Na+ ions move into the cell at a rate of 3.03E-7 mol/m^2*s. How much power must be produced by the "active Na+ pumping" system to produce this flow agaisnt a +33.9 mV potential difference? Assume that the axon is 12.0 cm long and 20.4 um in diameter. I do not understand how to go about this question, and how do I incorporate the rate into it as well? Could somebody please help me. Thanks a lot.
