With Facilitated Diffusion, how are the molecules moved across the cell membrane?
Facilitated diffusion is a process by which molecules are moved across the cell membrane with the help of transport proteins. These transport proteins create channels or carriers that allow specific molecules to pass through the membrane, from an area of high concentration to an area of low concentration.
The molecules bind to these transport proteins, which undergo a conformational change to move the molecules across the membrane. This allows for the selective transport of certain molecules that may be too large or polar to pass through the lipid bilayer of the cell membrane on their own.
Overall, facilitated diffusion allows for the passive movement of molecules across the cell membrane without the use of energy, relying instead on the concentration gradient of the molecules.
