What allows the movement of sodium ions into the neuron and potassium ions out of the neuron to cause firing?
A)gating mechanisms contained within the cell wall
B)changes in the chemical structure of the ions
C)changes in the charge of the ions
D)refraction

Question

Quizplus · Accepted Answer

Gating mechanisms contained within the cell wall, specifically voltage-gated sodium and potassium channels, are responsible for the movement of sodium ions into the neuron and potassium ions out of the neuron during the action potential, leading to neuronal firing.
