Vedclass · Answer

(A) In a resting neuron,the axonal membrane is significantly more permeable to potassium ions $(K^+)$ than to sodium ions $(Na^+)$.This high permeability to $K^+$ is due to the presence of numerous 'leak' channels for potassium in the axonal membrane.Conversely,the membrane is nearly impermeable to $Na^+$ ions during the resting state.This selective permeability,combined with the action of the $Na^+-K^+$ pump,helps maintain the resting membrane potential (approximately $-70 \ mV$).

When a neuron is not conducting any impulse,$i.e$.,resting,the axonal membrane is comparatively more permeable to:
