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 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 type of transport does a small molecule enter a cell with help from a membrane protein additional energy is needed to complete this process?
Facilitated
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.
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 process is used to move sugar molecules across a cell membrane?
I do believe that the answer is facilated diffusion.
Identify at least five ways by which a substance may enter the cell?
Osmosis, diffusion, facilitated diffusion, active transport, passive transport.
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

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.
