Question

What is the difference between a carrier protein and channel protein?

Answer 1

Carrier protein:

1. Carrier protein is a type of cell membrane protein that helps things leave or enter the cell by facilitated diffusion and active transport.

Channel protein:

A channel protein, which is a form of transport protein, works as a pore in the membrane, allowing tiny ions or water molecules to pass through fast.

S.No.	Carrier Protein	Channel Protein
1.	Carrier proteins transport molecules.	Channel proteins transport ions.
2.	Flip between two conformations.	The position is fixed.
3.	Have low transport rates.	Have high transport rates.
4.	Solute molecules are bound to one side and released from the other side.	Solute molecules diffuse through the pores.
