KnowraFacilitated diffusionLinked fromLinked fromThe 9 pages that link to Facilitated diffusion, each with the reason it gives.All 9Broader topic 2Related 3Narrower topic 1Compared with 3Ion channelNarrower topic: Ion channels are one route for this energy-independent membrane transport.Plasma membraneRelated: It lets selected polar molecules cross without the membrane’s hydrophobic core blocking them.Active transportCompared with: It uses transport proteins but does not move substances uphill.Concentration gradientRelated: Membrane proteins let some substances follow gradients they cannot cross unaided.ChemiosmosisCompared with: It involves downhill transport but does not necessarily couple ion flow to cellular work.Membrane transportRelated: It lets polar solutes cross membranes without direct energy expenditure.Passive transportBroader topic: Channels and carriers let ions and polar solutes cross membranes that lipids exclude.Gibbs–Donnan effectCompared with: Transport proteins mediate passage; Donnan partitioning concerns equilibrium across a barrier.Transport (biology)Broader topic: It lets polar molecules and ions cross membranes without ATP consumption.
