Question

What is sodium's role in an action potential? It flows out of the neuron causing the cell to depolarize. It gets pumped into the neuron allowing the cell to regain resting potential after the action potential is finished It flows into the neuron causing the cell to depolarize. It gets pumped out of the neuron causing the cell to repolarize
