because those that can't get through the membrane by themselves can get help. transport proteins give them a ride through the membrane. different transport proteins make it easier for certain molecules to get through the membrane without cell using energy
Energy actually isn't at all needed for facilitated diffusion. It is done with absolutely no cellular energy.
When the molecules are insoluble.
it isnt imortant
It does not require the use of the cells energy.
Facilitated diffusion is a type of passive transport which does not require the cell to expend energy.
beceause it just does
In cells, passive diffusion is energy independent and therefore does not require ATP. This is opposed to active transport which requires either energy in the form of ATP or a charge gradient to move a molecule or ion across the membrane.
Facilitated diffusion requires energy. This is because facilitated diffusion is the transfer of molecules from a lower concentration to a higher concentration.membrain pouch
Facilitated diffusion requires membrane proteins
No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
"Active Transport" is the answer given but if it is the passive movement then no energy is required so isn't it facilitated diffusion?
facilitated diffusion
It does not require the use of the cells energy.
Cells do not gain (or use) energy through facilitated diffusion.

Facilitated diffusion is a type of passive transport which does not require the cell to expend energy.
Facilitated diffusion is a type of diffusion specifically for larger molecules, to help them cross a selectively permeable membrane with the help of integral proteins that act as carriers. Facilitated diffusion is a passive process, i.e. it does not need energy/ATP.
simple and facilitated diffusion don't require energy and are forms of passive transport. Active transport requires energy
beceause it just does
Facilitated diffusion.
