What is faciillitated diffusion?
Facilitated diffusion is diffusion that occurs not through the cell membrane directly but through protein channels within the cell membrane. They are often, although not always, substrate specific.
What form of passive transport always requires membrane-bound proteins?
Facilitated diffusion
Facilitated diffusion required what?
Facilitated diffusion requires membrane proteins
Where diffusion occur?
Diffusion occurs on the cell membrane.
Which term refers to the diffusion of water throughout a membrane?
Osmosis is the diffusion of water through a membrane (semipermeable) membrane. Water always moves from a high concentration of water to a low concentration of water.
Small particles pass though passage waysin the cell membrane is called?
diffusion. osmosis is when it is water. and water only.
Diffusion requires what?
Facilitated diffusion requires membrane 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.
Is a specialized form of diffusion and diffusion is a type of passive transport?
membrane
Is a specialized form of diffusion and diffusion is a type of passive transport.?
membrane
The rate of diffusion through a semipermeable membrane will be lowest when?
The rate of diffusion through a semipermeable membrane will be lowest when temperatures are low. Lower temperatures decrease the energy of the molecules, which in turn decreases the rate of diffusion.
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.
