For which cation are there the largest number of leakage channels in the plasma membrane?
Which two factors involving ion diffusion determine the magnitudeof the resting membrane potential?
There are differences in Na+, K+, and Cl- ion concentrations across the membrane. Knowing that ions like to flow down their respective concentration gradients explain how the movement of Cl- and K+ ions can result in membrane hyperpolarization.
