Passive diffusion occurs when you have unequal concentrations of solutes on either side of a permeable membrane, therefore facilitated diffusion shouldn't require a difference in solute concentration to drive it.

Does osmosis or facilitated diffusion require the presence of membrane channels?
facilitated diffusion
Is osmosis an example of facilitated diffusion or active transport?
No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
What does facilitated diffusion require the use of?
Mo
How is facilitated diffusion diferant froma an active transport?
Facilitated diffusion is a type of passive transport which does not require the cell to expend energy.
Does the facilitated diffusion not require the cell to use energy?
It does not require the use of the cells energy.
Does facilitated diffusion require the use of special membrane proteins?
no
Is facilitated diffusion an active transport?
no it is not because it does not require the use of ATP
What are the three transport processes that do not require cell energy?
Passive Transport,Facilitated Diffusion, and Simple Diffusion
Diffusion with a channel protein?
They are the channels by which molecules enter in facilitated diffusion.
How is active transport different than simple and facilitated diffusion?
simple and facilitated diffusion don't require energy and are forms of passive transport. Active transport requires energy
Do cells gain and then use energy through facilitated diffusion?
Cells do not gain (or use) energy through facilitated diffusion.
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
