Background and context
Ions on both sides of the cell membrane strive for equilibrium and maintain the same concentration on both sides at all times. Ions migrate from a high concentration to a low concentration through passive transport. However, the ionic concentration on both sides is never the same. This is essential for the natural functioning of biological processes. Certain membrane proteins use adenosine triphosphate to transport molecules against the concentration gradient.
