What macromolecule is involved in facilitated diffusion?
Facilitated diffusion involves the transport of molecules across the cell membrane with the help of transport proteins. These transport proteins are typically made up of proteins, which are macromolecules. Therefore, macromolecules involved in facilitated diffusion are proteins.
What is the difference between passive diffusion and facilitated diffusion?
Passive diffusion is the movement of molecules across a cell membrane from an area of high concentration to low concentration without the need for a protein carrier. Facilitated diffusion, on the other hand, requires the presence of specific protein channels or carriers to help molecules move across the membrane.
What does active transport and facilitated diffusion have in common?
Both active transport and facilitated diffusion are methods of moving substances across cell membranes. Active transport requires energy input to move substances against their concentration gradient, while facilitated diffusion does not require energy and moves substances along their concentration gradient with the help of transport proteins.
Is diffusion through ion channels a form of active transport?
Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
Facilitated diffusion depends on?
Facilitated diffusion depends on the presence of specific transport proteins in the cell membrane that help to transport specific molecules across the membrane. These transport proteins facilitate the movement of molecules down their concentration gradient, without requiring energy input from the cell.
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
Does facilitated diffusion require the use of energy?
Facilitated diffusion does not require the use of energy.
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 are the 3 types of diffusion?
simple diffusion, osmosis and facilitated diffusion.
How much ATP does the Facilitated diffusion cost the cell?
Facilitated diffusion is an inactive mode.So no ATP cost.
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.
What is the use of carrier proteins for diffusion?
facilitated diffusion.
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.
