It's not clear to me that any biological system is understood at this level of detail. Any simulation is likely to be garbage-in, garbage-out. And even if it were fully understood, there's not enough computing power on the planet to model every atom and every molecule.
The map is not the territory, people. All models are wrong, but some are still useful. The ability to make simplifying assumptions is the whole point.
