Question
When comparing and contrasting facilitated diffusion and active transport, which statements are correct? Check all that apply.Check All That ApplyFacilitated diffusion does not involve membrane proteins; active transport does involve membrane proteins.Facilitated diffusion does not involve membrane proteins; active transport does involve membrane proteins.Facilitated diffusion does not require cellular energy; active transport does require cellular energy.Facilitated diffusion does not require cellular energy; active transport does require cellular energy.Facilitated diffusion moves substances along their concentration gradients; active transport usually moves substances against their concentration gradient.Facilitated diffusion moves substances along their concentration gradients; active transport usually moves substances against their concentration gradient.Facilitated diffusion moves substances into the cell; active transport moves substances out of the cell
Solution
The correct statements when comparing and contrasting facilitated diffusion and active transport are:
-
Facilitated diffusion does involve membrane proteins, as does active transport. Both processes require the use of protein channels or carriers to move substances across the cell membrane.
-
Facilitated diffusion does not require cellular energy; active transport does require cellular energy. Facilitated diffusion is a passive process, meaning it does not require energy. On the other hand, active transport requires energy (usually in the form of ATP) because it is moving substances against their concentration gradient.
-
Facilitated diffusion moves substances along their concentration gradients; active transport usually moves substances against their concentration gradient. This means that facilitated diffusion moves substances from an area of high concentration to an area of low concentration, while active transport moves substances from an area of low concentration to an area of high concentration.
-
The statement "Facilitated diffusion moves substances into the cell; active transport moves substances out of the cell" is not necessarily correct. Both facilitated diffusion and active transport can move substances in either direction across the cell membrane, depending on the specific needs of the cell and the concentration gradients of the substances involved.
