What happens to atp after it binds to the protein?

Once ATP is used by the protein, the protein is able to change shape. So, for example: the cell membrane consists of many proteins, like integral and peripheral proteins. When the cell wants to carry out active transportation to transport substances against a concentration gradient into the cell, the carrier proteins on the membrane use ATP to change shape and transport the molecules into the cell through the gap in the proteins. And remember that energy is released when ATP is converted to Apple by ATPase enzymes.
I hope this helps.
