WebThe membrane proteins then grab one molecule and shift their position to bring the molecule into the cell. That's an easy situation of passive transport because the glucose is moving from higher to lower concentration. It's moving down a concentration gradient. If you needed to remove glucose, the cell would require energy. WebSummary. Diffusion is the passive movement of molecules from a high concentration to a lower concentration. Diffusion can also be facilitated by membrane proteins such as channels or carriers. Osmosis is a water-specific type of diffusion, where water moves from a high to a low concentration across a selectively-permeable membrane.
