-Which letter in the accompanying figure corresponds to a large influx of Na+ ions into the cell?

Question

Quizplus · Accepted Answer

The large influx of Na+ ions into the cell corresponds to the rapid depolarization phase of the action potential, which is represented by the sharp upward spike in the graph. This phase is where voltage-gated sodium channels open, allowing Na+ ions to rush into the cell, causing the membrane potential to become more positive. This is best represented by point B on the graph.
