Simple diffusion = flow of small molecules ALONG the concentration gradient, does NOT require energy.
facilitated diffusion = flow of molecules ALONG the concentration gradient with help of CARRIER PROTIENS or CHANNELS, does NOT require energy
active transport= flow of larger or charged molecules AGAINST their concentration gradient, REQUIRES input of ENERGY in the form of ATP.)
Facilitated transport occurs when a substance moves from an area of higher concentration to an area of lower without the aid of energy. Active transport involves additional energy as it is moving from a lower concentration into a higher concentration.
Active transport uses energy and goes against the concentration gradient
Facilitated diffusion doesn't require energy and uses ion channels or carrier proteins to move things down the concentration gradient.
Active transport requires the cell to use energy, while facilitated diffusion does not.
It isn't homie..

Active transport moves solutes against their concentration gradient; facilitated diffusion moves substances down their concentration gradient.
osmosis, active transport, facilitated transport, difussion,etc
No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
They are the channels by which molecules enter in facilitated diffusion.
In active transport, the molecules are carried against the force of diffusion. This is the opposite of facilitated transport. Also in active transport, energy in the form of ATP is required, since the molecules move against the normal flow. Note that energy is not needed in facilitated transport.

Facilated transport does not need to use energy but active transport does.

No. Facilitated diffusion is a type of passive transport.

simple and facilitated diffusion don't require energy and are forms of passive transport. Active transport requires energy
Active transport moves solutes against their concentration gradient; facilitated diffusion moves substances down their concentration gradient.
The sodium potassium pump requires ATP - i.e. it is involved in active transport, not facilitated transport.
osmosis, active transport, facilitated transport, difussion,etc
Both facilitated transport and active transport require the substance that passes the membrane to pass through intermembrane proteins. However, unlike active transport, facilitated transport does not require ATP because it is not actively going against the concentration gradient.
No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
