About this simulation

Experiment with diffusion, transport proteins, ATP-driven pumps and osmosis. Track concentration, conserved solute and water volume.

What students can explore

Can solute move against its concentration gradient? What moves across the membrane during osmosis?
Ideal well-mixed compartments with relative units and illustrative time. Osmosis moves water only. A generic pump uses one ATP unit per amount moved. Pressure, charge and real-cell bursting are not modelled; volume is bounded.
