Facilitated diffusion occurs when a substance is aided across a membrane by a special molecule called an ionophore. Ionophores allow some molecules to diffuse but not others, effectively speeding up the rate of diffusion of that molecule.
They are the channels by which molecules enter in facilitated diffusion.
Facilitated diffusion moves molecules through cell membranes passively.
facilitated diffusion
Facilitated diffusion uses integrated proteins that act as channels for ions or molecules to pass through.
No. Facilitated diffusion is a type of passive transport.
Yes
it enters most rapidly by facilitated diffusion!!
Facilitated Diffusion
facilitated diffusion
There are three forms of passive transport, or the movement of biochemical and other atomic or molecular substances across the cell membranes. They are: osmosis, simple diffusion or facilitated diffusion, and filtration.
No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
Facilitated diffusion requires membrane proteins
