Which property of the sodium-potassium pump allows it to function in active transport?

• Its ability to change shape using ATP energy

• Its ability to create new molecules

• Its passive diffusion mechanism

• Its ability to store potassium ions

What would likely happen if the sodium-potassium pump failed to function properly in a cell?
