Question

difference between carrier protein and ion channel

Answer 1

• Solutes diffuse through the pore of channel proteins, whereas career proteins bind solutes on one side of membrane and release it on the other side.

• Compared with channel proteins, carrier proteins have very slow transport rates.

• Unlike carrier proteins, channel proteins contain a pore, which facilitates the solute transportation.

• Unlike channel proteins, carrier proteins have alternate solute-bound conformations.

• Channel proteins are lipoproteins, while carrier proteins are glycoproteins.

• Carrier proteins can mediate both active and passive transport, while channel proteins can mediate only passive transport.
