How might you use a radioactive isotope to find out whether the oxygen in CO2 comes from sugar or oxygen gas?
Animals obtain energy through a series of chemical reactions in which sugar (C6H12O6) and oxygen gas (O2) are reactants. This process produces water (H2O) and carbon dioxide (CO2) as waste products.

To test if the oxygen in CO2 comes from sugar, you could supply sugar that contains radioactive oxygen. The CO2 produced would then be ...
When sugar and oxygen gas react in animal cells, the product is carbon dioxide. This solution explains how to determine whether the oxygen in CO2 derives from the sugar or oxygen gas.
