resting neuron. _____________________________________________________________________ Potassium is more permeable than sodium in a resting neuron. Membrane permeability to sodium is very low because there are only a few sodium leakage channels. 5. Discuss how a change in Na_ or K_ conductance would affect the resting membrane potential. ________________________________________________ A change in permeability would affect the intercellular and extracellular concentration of ions during resting

membrane to Na+ and K+ in a resting neuron is different because of the varying number of leak channels. A cell has more potassium leak channels and has a higher permeability compared to the fewer sodium channels resulting in a lower relative permeability. 5. Discuss how a change in Na+ or K+ conductance would affect the resting membrane potential. Your answer: The cells resting membrane potential is
