Vedclass · Answer

(B) The generation of a nerve impulse (action potential) is initiated by the rapid influx of sodium ions $(Na^+)$ into the neuron.When a stimulus is applied to a site on a polarized membrane,the permeability of the membrane to $Na^+$ ions increases significantly.This leads to a rapid influx of $Na^+$ ions,which causes the reversal of the polarity at that site,known as depolarization.This change in membrane potential is the fundamental step in generating a nerve impulse.

During the nerve impulse (action potential),which ion has the highest permeability in the membrane?

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