Which transport process requires a carrier molecule but does not use cellular energy?

Question

Quizplus · Accepted Answer

Facilitated diffusion requires a carrier molecule to transport molecules across the membrane, but it does not require cellular energy. Diffusion does not require a carrier molecule but also does not use cellular energy. Osmosis is a specific type of diffusion that involves the movement of water molecules and also does not require a carrier molecule or cellular energy. Active transport and endocytosis both require both a carrier molecule and cellular energy.
