D) iron.

Question

Quizplus · Accepted Answer

The correct electrolytes that enable nerves to respond to stimuli are sodium and potassium. Potassium and sodium ions have opposite charges, which allows for a rapid exchange of ions across the cell membrane, generating the electrical impulses that allow the nerve to transmit a signal. Chloride can also be involved in the process, but it primarily serves to maintain the balance of electrical charges within the cell. Phosphorus and iron do not play a direct role in nerve impulses.
