Question

what is the role of atp in active transport? it provides energy for moving substances against the concentration gradient it acts as a channel protein it stabilizes the cell membrane it helps in facilitated diffusion

Explanation:

Active transport moves substances against the concentration gradient, which requires energy. ATP (adenosine - triphosphate) is the energy - currency of the cell and provides the necessary energy for this process. Channel proteins are different molecules for facilitating the movement of substances, and ATP is not a channel protein. Stabilizing the cell membrane and facilitating diffusion are not the roles of ATP in active transport.

Answer:

It provides energy for moving substances against the concentration gradient
