The potential of Na+ across the membrane of a nerve cell, worked out with the Nernst equation, is positive. What is the reason?
The membrane is impermeable to Na+ at all times.
The pump moves Na+ in and K+ out.
There is much more Na+ outside than inside, so Na+ tends to enter.
There is much more Na+ inside than outside, so Na+ tends to leave.
