<span>C6H12O6 + O2 -> CO2 + H2O + energy, otherwise expressed as glucose plus oxygen converted into carbon dioxide plus water plus energy. It includes glycolysis, the Krebs Cycle, and oxidative phosphorylation to properly balance.
The finished equation should look like this: C6H12O6 + 6O2 -> 6CO2 + 6H2O + energy</span>
