During an action potential Na ions move into the cell at a r

During an action potential, Na^+ ions move into the cell at a rate of about 3 times 10^-7mol/m^2s. How much power must be produced by the \"active Na^+ pumping\" system to produce this flow against a +30-mV potential difference? Assume that the axon is 40 cm long and 30 nm in diameter.

Curent

I =(3*10^-7mol/m2-s)(6.02*10^-23ions/mol)(1.602*10^-19C/ion)*pi*0.4m*(30*10^-6m)

I=1.09*10^-6C/s

Power

P=VI =30*10^-3*1.09*10^-6

P=3.27*10^-8 Watts
