Cell membranes contain openings called ion channels that allow ionsto move from the inside of the cell to the outside. Consider an ionchannel 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 forapproximately 1.0 ms for the flow of Na+ ions with a potentialdifference across the cell membrane of about 65 mV. How many Na+ions travel through the channel?
