Cellular Energy and Ion Balance Quiz

ATP provides the energy for carrying out active transport.

Sodium-potassium pumps are membrane proteins that pump sodium ions out of the cell and potassium ions into it.

ATP provides the energy to keep the sodium-potassium pump working, which maintains a regulated balance of ions.
