Question

multiple select question select all that apply opening of sodium channels in the membrane of a neuron results in: a positive charge inside of the plasma membrane repolarization a negative charge inside of the plasma membrane depolarization

Explanation:

When sodium channels in a neuron's membrane open, sodium ions ($Na^+$) rush into the cell. This influx of positively - charged sodium ions makes the inside of the plasma membrane more positive than the resting state, leading to depolarization. Repolarization occurs when potassium channels open and potassium ions exit the cell. At rest, the inside of the plasma membrane is negatively charged relative to the outside, and the influx of positive sodium ions changes this to a positive charge inside.

Answer:

a positive charge inside of the plasma membrane, depolarization
