Which of the following is a correct difference between active transport and facilitated diffusion?
-active transport can move solutes in either direction across a membrane, but facilitated diffusion can only move in one direction.
-active transport involves transport proteins, and facilitated diffusion does not.
-facilitated diffusion can move solutes against a concentration gradient, and active transport cannot.
-facilitated diffusion involves transport proteins, and active transport does not.
-active transport requires energy from atp, and facilitated diffusion does not.

Active transport requires energy from ATP while facilitated diffusion does not

Explanation:

Active transport and facilitated diffusion with the use of channel and carrier proteins are both ways by which ions, polar and large molecules cross a selectively permeable membrane.

The major difference is that; Active transport transport these particles from a low to high concentration, which is against concentration gradient and hence, energy is required to perform the task

Facilitated diffusion transport from a high to low concentration, which is through a concentration gradient and hence, no energy is required to perform the task.
