By first labeling molecular oxygen and then body water with 18O in a rat, Lifson measured the 18O abundance in expired CO2 and found the oxygens in CO2 exchanged with the oxygen in water. Indeed, these two oxygen containing species were in rapid isotopic equilibrium due to the actions of what we now know is carbonic anhydrase (Lifson, 1966)
