Question

How is electric potential gradient maintained in the human body?

Answer 1

Answer:

In order to maintain the membrane potential, cells maintain a low concentration of sodium ions (Na+) and high levels of potassium ions (K+) within the cell (intracellular). The sodium-potassium pump moves three Na+ ions out of the cell and brings two K+ ions into the cell.
