Question

Quizplus · Accepted Answer

Facilitated diffusion is a passive process where a substance moves down its concentration gradient across a membrane with the help of a transport protein. Receptor-mediated endocytosis, phagocytosis, and exocytosis are all active processes that require energy to move substances across the membrane. Active transport also requires energy, and involves the movement of a substance against its concentration gradient.
