Question 4

Diff between diffusion and active transport

Answer 4

facilitated diffusion moves substances down their concentration gradient and active transport moves them against their gradient. facilitated diffusion does not rely on cellular energy and active transport does. facilitated diffusion uses channel or carrier proteins and active transport does not
