Solution
The correct option is D Sodium
The important ions of the nervous system are sodium and potassium (both
have 1 positive charge). The sodium and potassium ions are pumped in
opposite directions across the membrane building a chemical and
electrical gradient for each. These gradients can be used to drive other
transport processes and maintains the electrical activity of the
neurons.
Therefore, the correct answer is option D.
