Is a carrier protein a transport protein?

Posted January 22, 2024


Yes, a carrier protein is a type of transport protein that plays a key role in facilitating the movement of molecules across the cell membrane. Carrier proteins work by undergoing conformational changes to bind to specific molecules on one side of the membrane and transporting the molecules to the other side. Carrier proteins are one of two types of transport proteins. The other is channel proteins.
