Education
Watch particles cross a membrane by simple diffusion, osmosis, carrier-mediated transport and the sodium-potassium pump, with a particle view and a smooth concentration curve side by side so you can see random motion produce predictable averages. Facilitated diffusion saturates while simple diffusion stays linear, and turning the pump off lets the gradients run down. Set the ion concentrations and permeabilities and the app computes Nernst potentials and the resting membrane potential from the Goldman-Hodgkin-Katz equation, showing where a cell's voltage comes from.
