Passive Transport A Journey Down the Gradient Passive transport requires no energy expenditure by the cell Molecules move down their concentration gradient from an area of high concentration to an area of low concentration This movement is driven by the natural tendency towards equilibrium Diffusion The movement of small nonpolar molecules like oxygen and carbon dioxide across the membrane Facilitated Diffusion The movement of larger or charged molecules like glucose and ions through specialized protein channels embedded in the membrane This process speeds up the movement but still doesnt require energy Osmosis The movement of water across a selectively permeable membrane from an area of 2 high water concentration to an area of low water concentration Realworld Examples of
