The equation of cellular respiration is as follows:
6 O2 (g) + C6H12O6 (aq) $\rightarrow$ 6 CO2 (aq) + 6 H2O (aq) + ATP
How is the water produced expelled from the body (of course, after some of it is used)? Is it expelled in urine? Or is the water vapour we breath out actually the by-product of respiration? Or, is it expelled in both methods/ways?
