It's often used to transport nutrients across the epithelium of the gut. It's also used to reabsorb nutrients from filtrate in the kidney. Any time the body needs to move substances against their concentration gradient without wasting excess ATP, you might expect cells to use facilitated diffusion. Facilitated diffusion usually requires less ATP per molecule moved than does active transport.

What are the transport mechanisms used by capillaries?
Diffusion, Filtration, and Osmosis
What type of plasma membrane transport is used for exchange?
Diffusion
Is diffusion an example of active transport or passive transport?
Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).
Is diffusion a passive transport?
diffusion
What type of plasma membrane transport is used for gas exchange?
Diffusion
What is the different in osmosis and diffusion?
Diffusion is the transport of materials from a high concentration to an area of low concentration across a gradient.Osmosis is the term used for the diffusion of water.
What 3 ways can substances enter and leave a cell?
Substances can move in and out of a cell in several ways. Diffusion is when a substance will distribute itself in or out of a cell until the distribution on both sides of the cell is balanced. Active transport is when a cell transports a substance across the cell membrane that would not normally be able to pass through. Osmosis is the movement of water from areas with few dissolved dissolved substances to areas with high dissolved substances.
Is diffusion through ion channels a form of active transport?
Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
How does diffusion take place in the body?
P.I.S.O.- Potassium in Sodium out facilitated diffusion, active transport , and passive transport and simple diffusion.
