ATP binds to the protein, releasing energy through hydrolysis to power a change in the protein's shape. Depending on how the cell pays for the
Specific molecules or ions (like sodium) bind to a carrier protein on the side of the membrane where they are scarce. Answer and Explanation: Cells use active transport to
The new shape allows the protein to "spit out" the molecules on the other side of the membrane, even though that side is already crowded with them.
To pull off this feat, cells use specialized membrane proteins often called . Here is a typical step-by-step breakdown of how a pump (like the famous sodium-potassium pump) operates:
