What happens during the process of facilated diffusion?

Answer 1

the diffusing substances first binds selectively to facilitative transporter, then transported across membrane by the change of confirmation of the protein, this process is called as facilitative diffusion

Answer 2

Facilitated diffusion is a form of transportation that molecules or ions use to move across a biological membrane. Facilitated diffusion is a passive transportation method that does not require energy from ATP.

Answer 3

This is where diffusion happens down the concentration gradient i.e. from high to low concentrations (just like simple diffusion) but facilitated diffusion requires a special and specific protein within the cell membrane. The substate binds to the receptor and the receptor itself changes conformation so that the substrate is now on the other side of the membrane. This is done for molecules that are too large to pass straight through the phospholipid bilayer (cell membrane) by simple diffusion e.g. glucose.
