In facilitated diffusion, molecules only move with the aid of a protein in the membrane. Simple diffusion is passive but facilitated diffusion is an active process that uses energy. Simple diffusion requires molecules to move through special doorways in the cell membrane.Click to see full answer. In this way, what is the difference between simple diffusion and facilitated diffusion quizlet?In simple diffusion, molecules move down the concentration gradient but in facilitated diffusion molecules move up the concentration gradient. In facilitated diffusion, molecules only move with the aid of a protein in the membrane.Also, what is the similarity between simple diffusion and facilitated diffusion? They both work with the concentration gradient which means they go from a high concentration area to a low concentration area. The differences are simple diffusion just goes though the membrane of a cell while facilitated diffusion uses a protein channel. Moreover, what is the difference between simple diffusion facilitated diffusion and osmosis? Facilitated diffusion is the movement of a molecule from an area of high concentration to an area of lower concentration with the help of a protein channel or carrier. Osmosis is the diffusion of water through a semi-permeable membrane.How is active transport different from simple diffusion and facilitated diffusion?Comparing Facilitated Diffusion and Active Transport. This process is called passive transport or facilitated diffusion, and does not require energy. The solute can move “uphill,” from regions of lower to higher concentration. This process is called active transport, and requires some form of chemical energy.
