What causes the membrane potential to return to the normal negative value after an action potential has occurred? A)opening of a voltage-gated K⁺ channel B)opening of a voltage-gated Na⁺ channel C)closing of a voltage-gated K⁺ channel D)opening of a ligand-gated Na⁺ channel E)opening of a voltage-gated K⁺ facilitated transporter

Question

Quizplus · Accepted Answer

The opening of voltage-gated potassium (K+) channels allows K+ to flow out of the neuron, which helps to restore the negative membrane potential after an action potential.
