Vedclass · Answer

(A) During the resting state,the axonal membrane is more permeable to $K^+$ ions and nearly impermeable to $Na^+$ ions. When a stimulus is applied at a site on the polarized membrane,the permeability of the membrane to $Na^+$ ions increases significantly. This leads to a rapid influx of $Na^+$ ions into the cell,which causes the reversal of the polarity at that site,known as depolarization. Therefore,the correct answer is that $Na^+$ ions move rapidly into the cell.

When a neuron is not conducting any impulse,the axonal membrane is comparatively more permeable to $K^+$ ions and nearly impermeable to $Na^+$ ions.

Assertion: The imbalance in concentration of $Na^+$,$K^+$ and proteins generates resting potential.
Reason: To maintain the unequal distribution of $Na^+$ and $K^+$,the neurons use electrical energy.
