Question

Quizplus · Accepted Answer

Facilitated diffusion is the movement of molecules across the cell membrane from a region of higher concentration to a region of lower concentration, with the help of specific transport proteins. This process does not require energy, such as ATP, to occur. Therefore, option A, which states that facilitated diffusion requires a specific transport protein to help nutrients move through the cell membrane, is the best choice.
