Question

Quizplus · Accepted Answer

Facilitated diffusion is a form of passive transport that involves a carrier molecule which helps the movement of molecules across the membrane according to their concentration gradient. It does not require energy expenditure and is not about moving molecules against their concentration gradient. It can involve various molecules, including proteins, but it is not specifically about how proteins enter the cells.
