Sign in to playAdd substances on either side of the cell membrane, then insert channel proteins, carriers and pumps to see how they cross. Four screens: Simple diffusion (O₂ and CO₂ through the phospholipid bilayer), Facilitated diffusion (leak channels, gated channels, glucose carrier), Active transport (ATP-driven Na⁺–K⁺ pump, Na⁺–glucose cotransporter) and a Playground that combines everything. Based on the "Membrane Transport" simulation by PhET Interactive Simulations, University of Colorado Boulder (CC BY 4.0); rewritten.
