What is facilitated diffusion and how does it differ from symport and antiport transportation? How do symport and antiport differ from each other?
Homework Answers
Facilitated diffusion is a passive transport by which molecules are transported through biological membrane by some proteins from high concentration region to low concentration region. It does not require energy.
In facilitated diffusion, there is a movement of molecules along the concentration gradient and does not require energy. But in antiport and symport,both are a type of secondary active transport in which movement is against the concentration gradient and it requires energy.
In symport , two molecules move in same direction. But in antiport, molecules move in opposite direction.

A correct distinction between facilitated diffusion and active transport of a substance across a biological membrane is that . . . A. active transport requires conformational changes in the transport protein associated with the transport process, and facillitated diffusion does not. B. active transport requires integral membrane protein to carry out the transport, and facillitated diffusion does not. C. facilitated diffusion depends on an existing energy gradient acting on the transported substance, while active transport makes such a gradient. D....
