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 diffusion doesn't require energy and uses ion channels or carrier proteins to move things down the concentration gradient.

Compare and contrast active transport and facilitated diffusion-?
Active transport moves solutes against their concentration gradient; facilitated diffusion moves substances down their concentration gradient.
What does the cell transport include?
osmosis, active transport, facilitated transport, difussion,etc
Is osmosis an example of facilitated diffusion or active transport?
No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
Diffusion with a channel protein?
They are the channels by which molecules enter in facilitated diffusion.
How do faciliated diffusion and active transport differ?
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.

How is facilitated transport different from active transport?
Facilated transport does not need to use energy but active transport does.
What are Vesicle mediated transport is a type of?
facilitated diffusion, secondary active transport and active transport
What are Vesicle-mediated transport is a type of?
facilitated diffusion, secondary active transport and active transport
Is facilitated diffusion active?
No. Facilitated diffusion is a type of passive transport.
Is facilitated diffusion an example of active transport?
no
How does facilitate transport differ from active transport?
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.
How is active transport different than simple and facilitated diffusion?
simple and facilitated diffusion don't require energy and are forms of passive transport. Active transport requires energy
Compare and contrast active transport and facilitated diffusion-?
Active transport moves solutes against their concentration gradient; facilitated diffusion moves substances down their concentration gradient.
Does facilitated transport have a sodium potassium pump?
The sodium potassium pump requires ATP - i.e. it is involved in active transport, not facilitated transport.
What does the cell transport include?
osmosis, active transport, facilitated transport, difussion,etc
How is faciliated transport similar to active transport?
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.
Is osmosis an example of facilitated diffusion or active transport?
No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
