6) The "undershoot" phase of after-hyperpolarization is due to A) slow opening of voltage-gated sodium channels. B) rapid opening of voltage-gated calcium channels. C) slow restorative actions of the sodium-potassium ATPase. D) sustained opening of voltage-gated potassium channels. E) ions that move away from their open ion channels.

B) Rapid opening of voltage-gated calcium channels: This is also not the cause of hyperpolarization, as the opening of calcium channels would lead to depolarization. C) Slow restorative actions of the sodium-potassium ATPase: This is not the cause of Show more…
