Study Notes

Energy Source and Transport Type of Sodium-Potassium Pump

The primary energy source used by the sodium-potassium pump is ATP (adenosine triphosphate).
The sodium-potassium pump exhibits active transport, as it uses energy to pump ions against their concentration gradients.

Role of Sodium-Potassium Pump in Animal Cells

The main role of the sodium-potassium pump in animal cells is to maintain the proper balance of sodium and potassium ion concentrations.

Electrogenic Pump in Plants

The primary electrogenic pump in plants is the proton pump.
