facilitated diffusion does not require energy, as it travels from a higher concentration gradient to a lower one(passive transport). Pumps do require energy to function(Active transport). This energy needed is ATP.

The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.


the difference about the osmosis, facilitated diffusion, and the diffusion is that the Osmosis is the diffusion of water across a membrane. facilitate


Facilitated diffusion does not require energy from a cell because transport relies on molecular binding. There is a difference in temperature with facilitated diffusion.


Requires the utilization of chemical energy. Another has said that Atp is not utilized.


The main difference is that in simple diffusion molecules are brought in or out by cell membrane while in facilitated diffusion through carrier proteins (from region of higher concentration to lower concentration).


Passive diffusion is what naturally happens without any assistance of any sort. Facilitated diffusion requires extra energy from extra sources to happen.


It would actually just be facilitated diffusion and diffusion. Facilitated diffusion needs an ion pump or a protein channel, but diffusion doesn't need anything like that. Materials that use general diffusion can cross the cell membrane without energy or any special attention from the cell.


Facilitated diffusion (or facilitated transport) is a process of diffusion, a form of passive transport facilitated by transport proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane.


Facilitated diffusion uses integrated proteins that act as channels for ions or molecules to pass through.


Facilitated diffusion involves a carrier protein (or channel).


Passive diffusion occurs when you have unequal concentrations of solutes on either side of a permeable membrane, therefore facilitated diffusion shouldn't require a difference in solute concentration to drive it.


Facilitated diffusion requires membrane proteins


Facilitated diffusion doesn't require ATP, active transport does. As a result, active transport is faster than facilitated diffusion. Active transport is against the concentration gradient and involves endocytosis. Facilitated diffusion is down the concentration gradient.


No. Facilitated diffusion is a type of passive transport.


no....ATP is not required during facilitated diffusion and that is why it is id passive. facilitated diffusion occurs with the help of carrier proteins


no! facilitated diffusion is passive therefore ATP is not required. facilitated diffusion is assisted by carrier and channel proteins


It seems obvious that the Answer is that facilitated diffusion requires bio-energy. Watchers rule [ruling] please.


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 does use transport proteins


In biology there are three types of diffusion. There are simple, channel, and facilitated diffusion.



Facilitated diffusion is a form of passive transport, in Facilitated diffusion molecules move across a semi-permeable membrane with the aid of specialized transports proteins and in active transport molecules move across the plasma membrane with the expenditure of ATP.


diffusion occurs naturally facilitated diffusion and active transport need energy


facilitated diffusion is the diffusion process enhanced by some external energy i.e. temperature, creating turbulance in medium
