question 1 - 4\nwhat is the difference between facilitated diffusion and active transport?\nfacilitated diffusion uses atp and moves substances with the concentration gradient; active transport does not.\nactive transport uses atp and moves substances against the concentration gradient; facilitated diffusion does not.\nactive transport uses atp and does not require a carrier protein; facilitated diffusion does neither.\nfacilitated diffusion uses atp and requires a carrier protein; active transport does not.

Answer

Brief Explanations:

Facilitated diffusion is a passive - transport process that moves substances along the concentration gradient and doesn't use ATP, but may use carrier proteins. Active transport uses ATP and moves substances against the concentration gradient.

Answer:

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