What happens when sodium potassium pump stops working?

 If this pump quits working (as happens under anoxic conditions when ATP is lost), or if the action of the pump is hindered (as happens with heart glycosides, for example, digoxin), Na+ aggregates inside the cell and intracellular K+ falls.

Explanation:

The way toward moving sodium and potassium particles over the cell layer is a functioning vehicle procedure including the hydrolysis of ATP to give the necessary energy. It achieves the vehicle of three Na+ to the outside of the cell and the vehicle of two K+ particles ions to the inside. In this manner, if the sodium-potassium siphon quits working both Na+ aggregates inside the cell and intracellular K+ falls.

the electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, x-rays, and gamma-rays.
