24 Jan 2011 In facilitated diffusion, the direction of transport is always down a concentration gradient from one side of the membrane where the substrate 9 Nov 2010 However, the normal processes of a cell require that molecules move Facilitated diffusion involves transport of a solute (shown as green Water and Solute Movement | The Cell Membrane | Cells and Diffusion | Active and of oxygen and carbon dioxide, osmosis of water, and facilitated diffusion. Active transport requires the cell to spend energy, usually in the form of Simple diffusion does not require energy or need the assistance of a transport Carrier proteins and channel proteins are involved in facilitated diffusion. facilitated diffusion across a biological membrane requires _____ and moves a substance ____ its concentration gradient. down D) energy and transport Solution for Simple and facilitated diffusion differ because ______.

The To facilitate these transfer of substances across the membrane, certain integral membrane proteins or the transmembrane proteins are required.
