B)Facilitated diffusion
C)Osmosis
D)Simple diffusion

Question

Quizplus · Accepted Answer

Active transport requires the use of a carrier protein to move molecules against their concentration gradient and energy in the form of ATP to power the movement. Facilitated diffusion only requires a carrier protein, but does not require energy. Osmosis and simple diffusion do not require carrier proteins or energy.
