Question

what is facilitated diffusion

Answer 1

N.B facilitated diffusion is not really diffusion, this is a passive transport across the cell membrane, it is called facilitated because the molecule being transported is carried by some proteins that are embedded in the membrane of cell(integral protein).

Answer 2

Facilitated diffusion is when a molecule cannot just passively diffuse across a membrane; however, it requires a protein "carrier" and energy in the form of ATP to move across the membrane

Answer 3

facilitated diffusion does NOT req ATP

Answer 4

Sorry my friend answered that one Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific trans-membrane integral proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism
