Consider a single ion channel (Problem 85) with During an action potential, this channel is open for approximately 1.0 ms for the flow of ions with a potential difference across the cell membrane of about 70 mV. How many ions travel through the channel?

(reference problem 85)

Cell membranes contain openings called ion channels that allow ions to move from the inside of the cell to the outside. Consider a typical ion channel with a diameter of 1.0 nm and a length of 10 nm. If this channel has a resistance of what is the resistivity of the solution in the channel?
