Which of the following events is NOT a characteristic of an action potential? A) The plasma membrane becomes highly permeable to Na⁺ and depolarization results. B) As Na⁺ enter, the inside of the plasma membrane becomes more negative. C) At the peak of depolarization, Na⁺ channels begin to close and K⁺ channels open. D) In repolarization, K⁺ flow out of the cell. E) Action potentials occur according to the all-or-none principle.
