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.
How is facilitated diffusion similar to diffusion ion channels?
Facilitated diffusion and diffusion ion channels both involve the movement of substances down a concentration gradient without requiring energy input. However, facilitated diffusion involves the assistance of carrier proteins to transport specific molecules, while diffusion ion channels are specialized proteins that form pores in cell membranes for specific ions to pass through.
Compare and contrast diffusion and facilitated diffusion?
Diffusion is the process by which particles move from an area of high concentration to an area of low concentration without the need for a transport protein. Facilitated diffusion is similar to diffusion but requires the assistance of specific transport proteins to move particles across a membrane. Both processes help maintain equilibrium within a cell or between cells and their environment.
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
