Quizplus · Accepted Answer

At the peak of the action potential, the electrical gradient for K⁺ tends to move the involved ion out of the cell. This is because at this point of the action potential, the electrical charge of the intracellular environment becomes more positive than the extracellular environment, creating a favorable environment for the positively charged K+ ion to exit the cell.
