If we could compute everything in a living system in polynomial time or better then we could design drugs inside of a computer and that technology would be worth billions! Seriously, until we are doing drug design with computers, we don't really understand biological systems well enough to simulate them inside a computer. Drugs interact with folded up proteins all the time so this requires simulation of protein folding and this algorithm is exponential time complexity, so basically not computable for anything but extremely trivial problems.
