It moves in the opposite direction. Na+/K+-ATPase is a catalyst found in the plasma layer. It is sodium-potassium adenosine triphosphatase, otherwise called the 'Na+/K+ pump', 'sodium-potassium pump', or essentially 'sodium pump', for short.
The chemical moves Na+ (sodium) particles out of the cell and replaces them with K+ (potassium) particles. This keeps the Na+ particles outside of the cell film and keeps the K+ particles within the cell layer. The procedure works the other way of dispersion.
