Question

Quizplus · Accepted Answer

When chemically gated Na⁺ channels open, positively charged sodium ions flow into the cell, causing a net positive charge on the inside of the cell. This results in depolarization of the membrane potential, meaning it becomes more positive. Therefore, the correct answer is C, depolarizes.
