How does the sodium-potassium pump work to transport sodium and potassium against their concentration gradient?

ATP hydrolysis provides the energy to transport ions against their concentration gradient.

Hydrogen ions set up an electrochemical gradient that drives the movement of sodium and potassium against their concentration gradient.

The net negative charge inside a cell pulls the sodium and potassium into the cell from their point of lower concentration outside the cell to a point of higher concentration inside the cell.

The potassium ions move through the pump by the process of facilitated diffusion.
