<h2>Answer</h2><h3>C) The proteins involved in active transport must be powered by ATP to work.</h3><h2>Explanation:</h2>
If we talk about active transport mechanisms, it means that the proteins basically require the use of the energy, that energy is usually in the form of adenosine triphosphate (ATP). but if we talk about the facilitated diffusion, then the solute can move from the regions of lower concentration to the region of higher concentration. In this way, the proteins used for active transport different from those used for facilitated diffusion.
