Diffusion happens on its own, but moving against the gradient costs ATP.

About this app
Transport Across the Cell Membrane is an interactive high-school biology simulation covering diffusion, osmosis, and active transport. Adjust concentration, solution type, cell type, ATP supply, and pump cycles to observe particle movement, water movement, cell shape changes, and sodium-potassium pump behavior. Mission-based activities provide guided practice with concentration gradients, tonicity, plasmolysis, and the 3:2 Na⁺-to-K⁺ transport ratio.
Use cases
- High-school biology students learning membrane transport
- Teachers demonstrating diffusion and osmosis in class
- Learners reviewing Cell Biology 1 concepts interactively
- Science experiment activities on concentration gradients
- Students practicing active transport and ATP concepts
Features
- Interactive Diffusion, Osmosis, and Na⁺/K⁺ Pump tabs
- Adjustable outside and inside concentrations for diffusion
- Hypotonic, isotonic, and hypertonic solution settings
- Red blood cell and plant cell osmosis examples
- ATP toggle and pump-cycle controls showing 3 Na⁺ out and 2 K⁺ in
- Guided missions with reset and next controls
