Function of channel and carrier proteins
WebThey allow substances to flow through them from high concentration to to low concentration without using any energy. That's what he meant by "with the concentration gradient." On … WebWhen a dopamine molecule binds to a dopamine receptor protein, a channel within the transmembrane protein opens to allow certain ions to flow into the cell. Some integral membrane proteins are glycoproteins. A glycoprotein is a protein that has carbohydrate molecules attached, which extend into the extracellular matrix. The attached ...
