For sodium to accumulate rapidly inside a neuron cell membrane,
A) a stimulus above the threshold must open sodium gates in an accelerating manner.
B) the wave of repolarization must occur to reestablish a resting potential.
C) there must be a dramatic increase in the negative charge of the cytoplasm.
D) a voltage surge must cause the sodium gates to close.
E) the potassium gates must open first.

Question

Quizplus · Accepted Answer

A stimulus above the threshold opens sodium gates, allowing sodium ions to flow into the neuron, leading to rapid depolarization and accumulation of sodium inside the cell.
