What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
What type of diffusion is specific and passive and becomes saturated if all of protein carriers are in use?
facilitated diffusion
Describe how glucose molecules enter a cell by facilitated diffusion?
protein
Why do you have diffusion?
so molecules can use protein channel to cross a cell membrane-cleo
What role do carrier protiens play in facilitated diffusion?
facilitated diffusion is also called cell-mediated diffusion because a substance transport in this manner diffuses through the membrane using a specific carrier protein to help.first, carrier protein binds to the binding site of the carrier protein ,and then there is a conformational change in the shape of the carrier protein that helps the molecule to diffuse other side of the membrane.
Does diffusion require a protein?
No.
Diffusion with a channel protein?
They are the channels by which molecules enter in facilitated diffusion.
Is facilitated 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 is the difference between diffusion and facilitate diffusion?
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
What is the similarity between simple diffusion and facilitated diffusion?
both need transport protein
Did NaCl require a transport protein?
Did NaCl require a transport protein for diffusion?
Is facilitated diffusion type of active transport?
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
How are the 3 passive transports different?
Simple diffusion - High concentration to low concentration, no energy required osmosis - Movement of water across a membrane, no energy required facilitated diffusion - Movement of substances, protein's are used to help move the substances across the membrane. There are very basic summaries of each.
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.

What is diffusion assisted by special protein molecules which bind to substances that diffuse across membranes?
facilitated diffusion
