Question

question 1-5
what is the difference between facilitated diffusion and active transport?
facilitated diffusion uses atp and moves substances with the concentration gradient; active transport does not.
active transport uses atp and moves substances against the concentration gradient; facilitated diffusion does not.
active transport uses atp and does not require a carrier protein; facilitated diffusion does.
facilitated diffusion uses atp and requires a carrier protein; active transport does neither.

Explanation:

Facilitated diffusion is a passive - transport process that moves substances down their concentration gradient with the help of carrier or channel proteins and does not require ATP. Active transport uses ATP to move substances against their concentration gradient.

Answer:

Active transport uses ATP and moves substances against the concentration gradient; facilitated diffusion does not.
