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:

Active transport in muscle cells often involves the calcium - ATPase pump (also known as the calcium pump). It uses ATP (adenosine - triphosphate) as an energy source to move calcium ions against their concentration gradient. The proteins involved in this process are carrier proteins which change their shape to facilitate ion movement across the cell membrane.

Answer:

calcium; ATP; against; carrier; shape
