Is the inside of the plasma membrane negative or positive relative to its outside in a polarized membrane of a resting cell?
The sodium-potassium pump generates the following concentration gradients across the plasma membrane:
high [Na"] and [K*] inside the cell and low [Na*] and [K] outside.
high [Na ] and low [K] inside the cell and low [Na] and high [K] outside.
low [Na] and [K*] inside the cell and high [Na*] and [K*] outside.
low [Na"] and high [K*] inside the cell and high [Na] and low [K] outside.
