Vedclass · Answer

(A) The resting membrane potential of a neuron is primarily maintained by the differential permeability of the axonal membrane to ions.Specifically,the membrane is much more permeable to potassium ions $(K^+)$ than to sodium ions $(Na^+)$.Due to the action of the $Na^+/K^+$ pump,$K^+$ ions diffuse out of the cell down their concentration gradient,leaving behind negatively charged proteins and organic anions inside the cell.This efflux of $K^+$ ions creates an electrical charge difference across the membrane,making the inside of the neuron electrically negative relative to the outside.

$A$ neuron becomes an electrically charged cell primarily due to the differential permeability and diffusion of which ion?
