Pore protein Versus Carrier protein

The protein molecule that forms a channel or a pore is known as channel or pore protein, while the protein that acts as a carrier is known as carrier protein.

Both are transport proteins which regulate the movement of water-soluble molecules and ions through the plasma membrane.

Carrier protein· a protein which transports specific molecules or ions pass through the plasma membrane in which it is embedded and into the cell.

What is the difference between the behavior of Channel Protein and Pore protein?

Answer:
Channel proteins do not require the binding of a molecule and conformational change to open.
Channel proteins allow molecules to diffuse across the membrane through diffusion .
whereas
Carrier protein allow specific molecules to cross the cell membrane by undergoing a conformational change upon the binding of the molecule.
The conformational change opens a hole through which the molecule can enter or exit a cell.


***Carrier protein is used in BOTH facilitated diffusion (which is a passive transport) and Active traansport!!

* I hope the pics help ! Soffea..
Pls check substances which can pass tru by these two methods!
