Answer:

C. ATP is required to move substance A into the cell.

Explanation:

As the model shows a cell with the movement of substances A and B, so the correct statement following the model is "ATP is required to move substance A into the cell".

This is so because ATP is required by a cell to move the substance such as ions across a membrane against a concentration and at the same time another substance moves out of the cell by the process called diffusion.

<u>As in the model, we can see substance A is moving in the cell while B is moving out of the cell (distance between cell membrane and substance B is more).</u>

Hence, the correct answer is "C. ATP is required to move substance A into the cell."
