1- During an action potential, Na+Na+ ions move into the cell at a rate of about 3×10−7mol/m2⋅s3×10−7mol/m2⋅s. How much power must be produced by the "active Na+Na+ pumping" system to produce this flow against a +30−mV+30−mV potential difference? Assume that the axon is 60 cmcm long and 30 μmμm in diameter. Express your answer using two significant figures. 2- A 4.80-mm length of 2.6-mmmm-diameter wire carries a 850 mAmA current when 19.0 mVmV is applied to its ends. If the...
