Question

one type of active transport is called the ____________ pump which helps muscle cells contract. this pump uses __________ to move ions __________ the concentration gradient. the protein that is used to pump the ions through is called a __________ protein and it changes its ____________ to move the ions across the cell membrane. label and color the carrier proteins red and the ions green.

Explanation:

The sodium - potassium pump is an important active transport mechanism in muscle cells. It uses ATP (adenosine - triphosphate) energy to move ions against their concentration gradient. Carrier proteins are involved in this process and change their shape to facilitate ion movement across the cell membrane.

The protein that is used to pump the ions through is called a carrier protein and it changes its shape to move the ions across the cell membrane.
(Regarding the label and color part, it is a practical task that cannot be done in text - based response. But the text - filling part is answered as above.)
