During an action potential, which of the following events occur?

Question

Quizplus · Accepted Answer

During an action potential, there is a rapid depolarization of the neuron's membrane potential, causing voltage-gated Na+ channels to open, allowing Na+ ions to flow into the neuron. This influx of positively charged ions results in a further depolarization of the neuron. As the membrane potential reaches its peak, the voltage-gated Na+ channels begin to close, and voltage-gated K+ channels open. This allows K+ ions to flow out of the neuron, repolarizing the cell and bringing the membrane potential back to its resting state. Therefore, during an action potential, Na+ flows into the neuron, followed by K+ flowing out of the neuron.
