When voltage-gated K⁺ channels open in the cell membrane of a neuron, K⁺ moves A) into the cell, and the membrane becomes hyperpolarized. B) into the cell, and the membrane becomes depolarized. C) out of the cell, and the membrane becomes depolarized. D) out of the cell, and the membrane becomes hyperpolarized. E) through the leak channels, and leak channels for Na⁺ are opened.

Question

Quizplus · Accepted Answer

When voltage-gated potassium (K+) channels open, K+ moves out of the cell, making the inside of the cell more negative relative to the outside. This process is known as hyperpolarization.
