movement. In a cell.
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.
Facilitated diffusion occurs when a membrane protein binds to a molecule on one side of the cell membrane and then releases it on the other side. This type of transport does not require energy and relies on the concentration gradient to move molecules across the membrane.
Facilitated diffusion moves molecules through cell membranes passively.
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.
No. Facilitated diffusion is a type of passive transport.
Facilitated diffusion is the specific and passive type of diffusion that becomes saturated when all protein carriers are in use. This occurs because facilitated diffusion relies on specific protein carriers to transport molecules across the cell membrane, and once all carriers are engaged, the rate of diffusion cannot increase further.
Facilitated diffusion requires membrane proteins
Facilitated diffusion does not require the use of energy.
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
Facilitated diffusion is diffusion that occurs not through the cell membrane directly but through protein channels within the cell membrane. They are often, although not always, substrate specific.
simple diffusion, osmosis and facilitated diffusion.
Facilitated diffusion is an inactive mode.So no ATP cost.
