$Na^{+}$

Vedclass · Answer

(C) The diagram represents the depolarization of a nerve fiber membrane. At the site marked $P$,the membrane potential changes from negative to positive inside due to the rapid influx of sodium ions $(Na^{+})$ through voltage-gated sodium channels. This influx of $Na^{+}$ ions causes the depolarization of the axonal membrane,which is the initial step in the generation of an action potential.

Which ions enter the cell at the site marked $P$ in the given diagram?
