How are the proteins used for active transport different from those used for facilitated diffusion?

The proteins for facilitated diffusion must attach to a carbohydrate to work.

The proteins used in facilitated diffusion create larger openings in the cell membrane.

The proteins involved in active transport must be powered by ATP to work.

The proteins that carry out active transport move only the largest molecules.
