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 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.
Does the facilitated diffusion not require the cell to use energy?
It does not require the use of the cells energy.
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 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.
How are diffusion and facilitated diffusion similar?
Substances enter a cell through the cell membrane
What three factors influence regulation in the cell membrane?
Diffusion, osmosis, and facilitated diffusion.
What substance crosses the cell membrane by facilitated diffusion?
a sodium ion
A molecule such as glucose must use a protein channel to cross through a cell membrane?
facilitated diffusion
How are diffusion and facilitated diffusion diffrent?

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.
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.
What carrier proteins help in facilitated diffusion in the cell membrane?
Integral proteins.
Does the facilitated diffusion not require the cell to use energy?
It does not require the use of the cells energy.
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.
