WebDec 14, 2024 · Facilitated diffusion is a process that does not require energy. This means that the cell does not have to expend any energy in order to move molecules … WebExplain why facilitated diffusion does not require energy from a cell. The solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. A cell is bathed in fluid. However, you notice that water is flowing out of the cell.

WebTranscript Passive transport is the movement of substances across a cell membrane without the use of energy. Examples include diffusion and facilitated diffusion. Active transport describes the use of energy to move molecules across a cell membrane, usually against their concentration gradients. Webfacilitated diffusion: the protein-mediated transport of a compound across a biomembrane that is not ion-driven; a saturable transport system.
