Cool visuals, but the explanations are rough

Be skeptical of the information provided as they are misleading. ATP synthase is described backwards, it makes ATP using proton flow, not the other way around. Great concept but the biology needs a fact check

Great app, but they should make more cells. It would be interesting to see something like this but with computers instead of cells.

CellWalk’s Brain Cell

That seems like comes from the bacteria brains that have a very strong immune system that can fight against viruses cells in the brain.
