Which statement is true of both active transport and facilitated diffusion? a. both require atp b. both move materials down a concentration gradient c. both occur in only one direction d. both involve proteins in the cell membrane

The correct answer is option (D) The active transport and the facilitated diffusion both involve the proteins present in the cell membrane.

Facilitated diffusion transport the large and the charged molecules through the protein transport channels present in the cell membrane. In this case, the solute move from a region of higher concentration to lower concentration and it does not require energy.

Active transports takes place when the molecules move from a region of lower concentration to higher concentration via the membrane protein channels.

Both facilitated diffusion and active transport requires the proteins present in the cell membrane.

D

Explanation:

Both involve proteins in the cell membrane.
