Facilitated diffusion helps molecules move across cell membranes by utilizing specific carrier proteins. It does not require energy input, as molecules move down their concentration gradient. This process is crucial for transporting larger molecules like glucose and ions across cell membranes.

What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
How is facilitated diffusion diferant froma an active transport?
Facilitated diffusion is a type of passive transport which does not require the cell to expend energy.
What type of diffusion helps glucose enter the cell?
facilitated diffusion
Are aquaporins involved in osmosis or facilitated diffusion?
Aquaporins are involved in osmosis by facilitating the movement of water molecules across cell membranes. They do not participate in facilitated diffusion, which involves the transport of solutes across membranes with the help of carrier proteins.
Three types of passive transport?
Simple diffusion: Small, non-polar molecules move across the cell membrane without the need for energy. Facilitated diffusion: Larger or polar molecules use carrier proteins to move across the cell membrane without energy expenditure. Osmosis: The movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
Is facilitated diffusion active?
No. Facilitated diffusion is a type of passive transport.
Facilitated diffusion required what?
Facilitated diffusion requires membrane proteins
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.
Does glucose enters a cell most rapidly by facilitated diffusion?
No, glucose enters a cell most rapidly through facilitated diffusion with the help of glucose transporters, such as GLUT proteins. Facilitated diffusion allows glucose to move down its concentration gradient into the cell without requiring energy.
How much ATP does the Facilitated diffusion cost the cell?
Facilitated diffusion is an inactive mode.So no ATP cost.
What are the 3 types of diffusion?
simple diffusion, osmosis and facilitated diffusion.
What is the use of carrier proteins for diffusion?
facilitated diffusion.
Do cells gain and then use energy through facilitated diffusion?
Cells do not gain energy through facilitated diffusion. Facilitated diffusion is a passive process in which molecules move across the cell membrane from an area of higher concentration to lower concentration with the help of transport proteins, without the need for energy input. Cells use energy through other processes such as active transport and cellular respiration to maintain their functions.
Diffusion requires what?
Facilitated diffusion requires membrane proteins
Is this true that Facilitated diffusion would be used on large molecules?
its false, facilitated diffusion would be used on small molecules
Diffusion with a channel protein?
Channel proteins facilitate the passive movement of molecules down their concentration gradient. They form channels across the cell membrane, allowing specific molecules to move in and out of the cell without requiring energy input. This process is known as facilitated diffusion.
