If the resting membrane potential is defined as when the rate of passive diffusion of ions equals the rate of the action of Na+/K+ pump, why is the resting potential negative?
I.e. the Na+/K+ pump actively transports 3 Na+ out for every 2 K+ in, but 3 Na+ are passively diffusing back in, and 2 K+ are passively diffusing back out.
