Interesting question, I don't know if anyone has looked into whether membranes might get "gummed up" by material getting stuck part way through. Watch the action of carriers and channels during facilitated diffusion. In osmosis, water always moves toward the __________ solution, that is, toward the solution with the __________ solute concentration. The opening and closing of these channels, and the resulting shifts in ion levels inside the cell, play an important role in electrical transmission along membranes (in nerve cells) and in muscle contraction (in muscle cells). B. First, it is happening thanks to the concentration gradient. Membrane Transport (1 of 4): Diffusion and Passive Transport (BioFlix tutorial) Cells require a constant exchange of solutes (ions and small molecules) with the outside of the cell. Active transport requires an input of energy and moves molecules against their concentration gradient. The passive movement of a solute across a membrane with the help of a transport protein is called facilitated diffusion.
