Both move materials down a concentration gradient.

Both move materials down a concentration gradient.

Answer 1

The statement that is true of both active transport and facilitated diffusion is:

Both involve proteins in the cell membrane.

Active transport requires energy (ATP) and moves substances against their concentration gradient, while facilitated diffusion does not require energy and moves substances down their concentration gradient, but both processes utilize membrane proteins.
