And no, oxygen doesn't build proteins directly. The main problem is that your body needs to keep burning sugar to keep your brain operating. The rest is to keep your heart pumping and your muscles working for any strenuous activity. No air means brain death because your body has to keep the lights on up there or brain tissue starts dying.
