Diffusion of K+ (and less Na+) leads to a separation of charges across the membrane, and the resting potential. – Remember: There are MANY K+ and very few Na+ channels, thus membrane permeability is 100x for K+ than Na+. – Movement of K+ increases the positive charge outside the membrane relative to ...
