The transport protein facilitates the movement of solute across the plasma membrane.. Membrane Transport -- Facilitated Diffusion Would it eventually work its way in, or would it get stuck in the membrane? This is because channel proteins are simple tunnels; unlike carrier proteins, they dont need to change shape and reset each time they move a molecule. Certain molecules use diffusion to cross the plasma membrane. Interesting question, I don't know if anyone has looked into whether membranes might get "gummed up" by material getting stuck part way through. There is net movement of molecules from the outside to the inside of the cell until the concentrations are equal on both sides.
