What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
How is the cell membrane facilitated diffusion transported?
In Facilitated diffusion materials are transported across the plasma membrane without using up any energy. Plasma membranes is made up of phospholipid bilayers consisting of proteins which help in the transportation of larger materials.
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
Why the line-with-gaps model is not suitable to explain facilitated diffusion?
Facilitated diffusion is a carrier-mediated form of transport across a membrane. The line-with-gaps model doesn't show the carrier proteins that are in the cell membrane. These proteins are what help facilitated diffusion occur.
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
What is facilited diffusion?
Facilitated Diffusion is the movement of molecules across cell membranes through protein channels and carrier proteins.Facilitated diffusion is a passive transport process, aka no energy required, where substances move down their concentration gradient (high concentration to low concentration) across a protein through a membrane protein because it is unable to diffuse directly through the phospholipid portion of the membrane itself.Diffusion of molecules assisted by protein channels that pierce a cell membrane

Facilitated diffusion across a biological membrane requires what?
transport proteins

The process where a nonpolar molecule can just passively get across a membrane is called?
facilitated diffusion

Explain the differences among diffusion facilitated diffusion and osmosis?
osmosis is the movement of water across the plasma or cell membrane
Facilitated diffusion sentence?
Facilitated diffusion is a type of diffusion specifically for larger molecules, to help them cross a selectively permeable membrane with the help of integral proteins that act as carriers. Facilitated diffusion is a passive process, i.e. it does not need energy/ATP.
What is meant by passive transport of material across a membrane?
"Passive" mean that it does not require energy, therefore the passive transport of material across the membrane means that it can transport the material (cells or whatever) without the function of energy across the membrane.
