So, in school we learn C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP

And C6H12O6 -> Lactic acid + energy

C6H12O6 -> Ethanol + energy

But if ATP is C10H16N5O13P3, how does that equation balance? Where are the Nitrogen and Phosphorus coming from? How come we never see anaerobic respiration written out in a full chemical equation with Ethanol as C2H6O or Lactic Acid as C3H6O3, and if we did what would that be?
