Cell membranes contain openings called ion channels that allow ions to move from the inside of the cell to the outside. Consider an ion channel with a diameter of 0.6 nm and a length of 14 nm with R = 109 O. During an action potential, this channel is open for approximately 1.0 ms for the flow of Na+ ions with a potential difference across the cell membrane of about 65 mV. How many Na+ ions travel through the channel?
