Answer 1

Facilitated diffusion primarily requires a **transport protein**. It does not require ATP, as it is a passive transport process that allows molecules to move across a cell membrane along their concentration gradient. The sodium-potassium pump and vesicles are not involved in facilitated diffusion. Therefore, the correct answer is:

- **transport protein**
