well, if what i learned in science is right their are 2 types of diffusion. 1 is passive transport and the other is active transport. Passive transport is regular. It is when the molecules and atoms go across the cell's membrane through tiny holes in it. the cell membrane allows things it needs to enter, but does not allow waste or dangerous things that will harm the cell in.

In facilitated diffusion, materials move through the cell membrane with the help of protein channels or carriers. These proteins create a passageway or binding site for specific molecules or ions to pass through the membrane. The movement is passive and follows the concentration gradient, meaning that molecules move from an area of higher concentration to an area of lower concentration.

What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
How are diffusion and facilitated diffusion diffrent?
Diffusion directly passes through the cell membrane unaffected by the hydrophobic part of the membrane. Facilitated diffusion uses proteins to assist in the movement of molecules. Ions have trouble moving through the hydrophobic part of the membrane.
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 are the functions of facilitated diffusion?
the point of facilitated diffusion is to help move sugars and amino acids through the cell membrane the ready set <3
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called?
Facilitated diffusion is the process by which glucose can pass through a cell membrane by combining with special carrier molecules.
What type of substances pass through the membrane by facilitated diffusion?
soluble materials which can diffuse passively .
What is the diffusion of water through the cell membrane is called?
Facilitated Diffusion
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.

What are the types of movement through a membrane?
Osmosis, diffusion, facilitated diffusion, active transport
How are diffusion and facilitated diffusion similar?
Substances enter a cell through the cell membrane
What is the process by which materials enter and leave the cell through the cell membrane?
Either active transport, passive transport, or facilitated 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
A molecule such as glucose must use a protein channel to cross through a cell membrane?
facilitated diffusion
What are the functions of facilitated diffusion?
the point of facilitated diffusion is to help move sugars and amino acids through the cell membrane the ready set <3
What types of transport mechanisms through the cell membrane are passive?
diffusion, facilitated diffusion, and osmosis
What is faciillitated diffusion?
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.
