What is the difference between diffusion and facilitated diffusion in terms of the movement of molecules across a cell membrane?
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. Facilitated diffusion also moves molecules from high to low concentration, but requires a specific protein to help them pass 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.
Does facilitated diffusion require energy for the movement of molecules across the cell membrane?
No, facilitated diffusion does not require energy for the movement of molecules across the cell membrane.
Does facilitated diffusion require energy for the transportation of molecules across the cell membrane?
Facilitated diffusion does not require energy for the transportation of molecules across the cell membrane.
Does facilitated diffusion require energy to transport molecules across the cell membrane?
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
Does facilitated diffusion require a transport protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion does require a transport protein for the movement of molecules across the cell membrane.
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
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.
Does facilitated diffusion require energy for the movement of molecules across the cell membrane?
No, facilitated diffusion does not require energy for the movement of molecules across the cell membrane.
Does facilitated diffusion require energy for the transportation of molecules across the cell membrane?
Facilitated diffusion does not require energy for the transportation of molecules across the cell membrane.
Does facilitated diffusion require energy to transport molecules across the cell membrane?
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
Does osmosis or facilitated diffusion require the presence of membrane channels?
Facilitated diffusion requires the presence of membrane channels or transporters to move molecules across the membrane. Osmosis, on the other hand, does not require membrane channels as it involves the passive movement of water molecules through the lipid bilayer of the membrane.
How do glucose molecules cross a plasma membrane?
Facilitated Diffusion
Does facilitated diffusion require a transport protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion does require a transport protein for the movement of molecules across the cell membrane.
Does facilitated diffusion require a carrier or channel protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion requires a carrier or channel protein for the movement of molecules across the cell 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 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.
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.
