How does Facilitated diffusion differs from diffusion in that facilitated diffusion?

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

How is facilitated diffusion similar to diffusion ion channels?

Facilitated diffusion and diffusion ion channels both involve the movement of substances down a concentration gradient without requiring energy input. However, facilitated diffusion involves the assistance of carrier proteins to transport specific molecules, while diffusion ion channels are specialized proteins that form pores in cell membranes for specific ions to pass through.


Three types of passive transport?

There are three forms of passive transport, or the movement of biochemical and other atomic or molecular substances across the cell membranes. They are: osmosis, simple diffusion or facilitated diffusion, and filtration.


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.


Facilitated diffusion required what?

Facilitated diffusion requires membrane proteins
