Facilitated diffusion:
Active Transport:
Comparison:
Active transport requires ATP and passive transport does not. Active transport goes against the concentration gradient and passive transport goes with the concentration gradient and includes osmosis, diffusion and facilitated diffusion.
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
The most essential difference is that one is active (uses energy) and one is passive (doesn't require energy). Take note whenever you see the word 'active' in this context- it denotes that energy is required for it to occur, usually against the concentration gradient. Facilitated diffusion is just another passive process by which molecules move from an area of high concentration to low concentration. Note that this requires no energy to occur, except it differs from diffusion in that a carrier molecule is required (usually because the molecule is too large to freely cross the plasma membrane)
Diffusion requires no energy as it follows the electrochemical gradient. Active transport requires energy (ATP), as it works against the electrochemical gradient.
Diffusion is the movement of molecules from areas of high concentration to areas of low concentration and active transport is the movement of molecules from an area of low concentration to an area of high concentration
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
Facilitated diffusion is a type of passive transport (does not require energy). It is called facilitated diffusion because it utilises the carrier protein to diffuse through it. Active transport requires energy to pump certain big molecules to cross over and this uses transport protein. Basically, the difference is just the usage of energy.
both need transport protein
Active transport requires ATP and passive transport does not. Active transport goes against the concentration gradient and passive transport goes with the concentration gradient and includes osmosis, diffusion and facilitated diffusion.
i don't know i need help pleas?
Passive diffusion is what naturally happens without any assistance of any sort. Facilitated diffusion requires extra energy from extra sources to happen.
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
Passive transport is a form of transport that does not require an input of energy. Examples include diffusion, osmosis and facilitated diffusion. On the other hand, active transport is a form of transport that requires an input of energy in the form of ATP (adenosine triphosphate). This energy is required for processes such as moving molecules against the concentration gradient.

Endocytosis is NOT an example of diffusion. It is an example of active transport whereas diffusion is a type of passive transport. The difference lies in the fact that diffusion does not require energy to take place, and endocytosis does.
Facilitated diffusion occurs in order to maintain homeostasis within a cell. If there is more of something, such as water, inside a cell than outside the cell, diffusion allows the water to flow out of the cell so that an equal amount of water molecules exists both inside and outside the membrane. This requires little or no energy from the cell itself. Active transport is when the cell takes in or excretes material through the membrane so that the amount of material inside and outside the membrane is different. This requires energy from the cell to occur.
