How do Na⁺ ions enter a neuron when an action potential is initiated? A)the Na⁺/K⁺-ATPase B)a gated Na⁺ pump C)a voltage-gated Na⁺ channel D)the ligand-gated Na⁺ channel E)a voltage-gated Na⁺ facilitated transporter

Question

Quizplus · Accepted Answer

During an action potential, the depolarization of the neuron's membrane potential triggers the opening of voltage-gated Na⁺ channels. This allows Na⁺ ions to enter the neuron and cause further depolarization, ultimately leading to the propagation of the action potential down the axon.
