When voltage-gated K⁺ channels open on the conductive segment of a neuron, A) potassium exits, repolarizing the cell to a negative value. B) potassium exits, depolarizing the cell to an even more negative value. C) potassium enters, depolarizing the cell to a positive value. D) potassium enters, repolarizing the cell to a negative value. E) potassium enters, repolarizing the cell to a positive value.

Question

Quizplus · Accepted Answer

When voltage-gated K⁺ channels open, potassium ions exit the neuron, causing the cell to repolarize and return to a more negative membrane potential.
