WebIn cells, some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly, while others must pass through membrane proteins in a process called facilitated diffusion. Here, we’ll look in more detail at membrane permeability and different modes of passive transport. WebStudents could show the water molecules moving past each other. Water Evaporates Have students use their molecules to model what would happen if the water was heated and the molecules evaporated. Students should show the water molecules moving faster and breaking away from the other molecules and entering the air. Water Vapor Condenses

WebTemperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Solvent density: As the density of the solvent increases, the rate of diffusion … WebRather the different concentrations of materials in different areas are a form of potential energy, and diffusion is the dissipation of that potential energy as materials move down their concentration gradients, from high to low. ...
