The sodium-potassium transporter keeps the intracellular concentration of sodium ions low by pushing them out of the axon.

Question

Quizplus · Accepted Answer

The sodium-potassium transporter, also known as the sodium-potassium pump, actively pumps sodium ions out of the cell and potassium ions into the cell to maintain a low concentration of sodium ions inside the axon. This helps to establish and maintain the resting membrane potential and also plays a role in generating action potentials.
