the process through which the molecule move from a higher concentrated to low concentrated is called as Osmosis. the same molecule when move from a high concentration to lower one is called as Reverse Osmosis.

This is due to random motion and no ATP is needed. Diffusion continues until the concentration of the molecule is equal on both sides of the 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 process is used to move sugar molecules across a cell membrane?
I do believe that the answer is facilated diffusion.
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
Assisted transport of a molecule across the cell membrane without an expenditure of energy is known as?
Any movement of molecules into or out of a cell without the expenditure of energy is called diffusion. If the molecule uses special channels to diffuse through the membrane (again, not expending energy), it is called facilitated diffusion.
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
How simple diffusion can be distinguished from facilitated diffusion?
simple diffusion transports smaller molecules like oxygen and water while facilitated diffusion transports larger molecules like glucose and requires energy
What is the process When proteins help molecules move across the membrane is called?
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
How is facilitated diffusion differing from diffusion?
Simple diffusion allows non-polar molecules to pass through and a little amount of H20. On the other hand, Facilitated diffusion allows ions and polar molecules across the membrane because it contains carrier proteins. It is highly specific to substances it diffuses across the membrane.
In what type of passive cell membrane transport do carrier proteins combine with specific molecules to assist them across the membrane?
Facilitated Diffusion

What is facilitated transport?
Facilitated diffusion (or facilitated transport) is a process of diffusion, a form of passive transport facilitated by transport proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane transport proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism.
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
What process is used to move sugar molecules across a cell membrane?
I do believe that the answer is facilated diffusion.
What is facilitated diffusion across the phospholipid membrane?
Facilitated diffusion is the movement a substance from high concentration to low concentration across a membrane through a transporter protein or channel
What is a form of transport that uses transport proteins to move other ions and small molecules across the plasma membrane?
facilitated diffusionfiltration
State how facilitated diffusion is achieved?
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.
