Facilitated diffusion is primarily mediated by two types of membrane proteins: channel proteins and carrier proteins. Channel proteins form pores or channels that allow specific ions or molecules to pass through the membrane down their concentration gradient. Carrier proteins, on the other hand, bind to specific substrates and undergo a conformational change to transport the molecules across the membrane. Both types enable the movement of substances that cannot easily cross the lipid bilayer.
What else can I help you with?
Which of the following types of membrane proteins are responsible for facilitated diffusion?
Channel proteins and carrier proteins are responsible for facilitated diffusion. Channel proteins form hydrophilic channels that allow specific ions or molecules to pass through the membrane, while carrier proteins undergo conformational changes to transport molecules across the membrane.
The carrier proteins that help in facilitated diffusion are what kind of proteins?
The carrier proteins that aid in facilitated diffusion are integral membrane proteins. These proteins are embedded within the cell membrane and undergo conformational changes to transport molecules across the membrane.
What is falicitated diffusion?
Facilitated diffusion is a type of passive transport where specific molecules are transported across the cell membrane with the help of transport proteins. Unlike simple diffusion, facilitated diffusion requires the presence of these proteins to facilitate the movement of molecules across the membrane.
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.
A form of passive transport that involves membrane proteins to aid in the movement of substances?
Facilitated diffusion is a form of passive transport that involves membrane proteins to aid in the movement of substances across a cell membrane. The membrane proteins act as channels or carriers to facilitate the passage of specific molecules that cannot freely diffuse across the lipid bilayer. This process does not require energy input from the cell.

What carrier proteins help in facilitated diffusion in the cell membrane?
Integral proteins.
Does facilitated diffusion require the use of special membrane proteins?
no
What is falicitated diffusion?
Facilitated diffusion is a type of passive transport where specific molecules are transported across the cell membrane with the help of transport proteins. Unlike simple diffusion, facilitated diffusion requires the presence of these proteins to facilitate the movement of molecules across the membrane.
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.
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.
How does Facilitated diffusion differs from diffusion in that facilitated diffusion?
Facilitated diffusion involves the use of carrier proteins to move specific molecules across the cell membrane, while simple diffusion does not require proteins and involves the movement of molecules from an area of high concentration to low concentration. Facilitated diffusion is selective and allows for faster transport of specific molecules that may be too large or polar to diffuse freely through the membrane.
What is the difference between facilitated diffusion and simple diffusion in terms of the mechanisms by which molecules move across a cell membrane?
Facilitated diffusion involves the movement of molecules across a cell membrane with the help of specific proteins, while simple diffusion does not require any proteins and relies on the molecules moving freely through the membrane.
