Vedclass · Answer

(A) During the repolarization phase of an action potential in a nerve fiber,the following events occur:$1$. The voltage-gated $Na^+$ channels close,preventing further influx of sodium ions into the cell.$2$. The voltage-gated $K^+$ channels open,allowing potassium ions to flow out of the cell.This efflux of $K^+$ ions restores the negative resting membrane potential inside the cell.Therefore,the correct events are $b$ ($Na^+$ channels close) and $d$ ($K^+$ channels open).

Which of the following events occur during the repolarization of a nerve fiber?

Differentiate between Resting potential and Action potential.

Give scientific reasons:
$(1)$ There is no physical connection between sequential neurons,yet nerve impulses are conducted through them.
$(2)$ The neuroplasm of a neuron contains a high $K^+$ concentration during the maintenance of the resting potential.
