Front | How is the resting potential established? |
---|---|
Back | - Na+ K+ ATPase actively transports 3 Na+ out and 2K+ in - membrane is more permeable to K+ and less permeable to Na+ - some K+ ions diffuse out through leakage K+ channels - diffusion slows as K+ ions repelled by positive charge outside axon - chemical and electrical gradients balanced - equilibrium established - no net movement of ions - 65mV |
