What are the main differences between facilitated diffusion and active transport?
Facilitated diffusion requires energy, while active transport does not.
Active transport requires energy, while facilitated diffusion does not.
Facilitated diffusion uses carrier proteins, while active transport does not.
Active transport can move molecules against the concentration gradient, while facilitated diffusion cannot.
Explanation
Active transport requires energy and can move molecules against the concentration gradient. Facilitated diffusion does not require energy and moves molecules down the concentration gradient.
