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

A. The proteins for facilitated diffusion must attach to a carbohydrate to work.
B. The proteins used in facilitated diffusion create larger openings in the cell membrane.
C. The proteins involved in active transport must be powered by ATP to work.
D. The proteins that carry out active transport move only the largest molecules.

Final answer:

Active transport proteins utilize ATP to move substances against concentration gradients, unlike facilitated diffusion proteins that do not require ATP.


Explanation:

Proteins for active transport require energy in the form of ATP to move substances against a concentration gradient, creating specific solute gradients. Various types of transporters, such as uniporters, symporters, and antiporters, are involved in this process. These proteins are distinct from those used in facilitated diffusion, as they necessitate energy input to function effectively.
