If a substance must move into the cell against its concentration gradient, the cell must use free energy, often provided by ATP, and carrier proteins acting as pumps to move the substance. Substances that move across membranes by this mechanism, a process called active transport, include ions, such as Na + and K +. greetings to customer in emailsWebWhy is it active transport? Because we're using ATP to drive sodium against its concentration gradient to keep pumping the sodium out of the cell, and then potassium kind of comes in, you could almost imagine, passively. It doesn't require ATP. And that's why this is often called a sodium-potassium ATPase, which means it's a protein or an ... ho wto shimmy sekiro
