<prompt> The permeability of which of the following ion leads to resting membrane potential?SodiumCalciumPotassiumChloride  <response>: Ionic Basis of Nerve Resting Membrane Potential RMP: Resting membrane potential is a potential difference across the cell membrane in millivolts, which is by convention -70 Mv. RMP is established by the diffusion potential that results from concentration differences of permeable ions. Resting membrane potential -70 mV is close to equilibrium potential of K and Cl both-85 mV and far from the equilibrium potential of Na 65 mV. That means at rest the nerve membrane is more permeable to K than Na Na is actively transported out of neurons and other cells and K is actively transported into cells, but because K permeability at rest is greater than Na permeability, K channels maintain the resting membrane potential.
