Cellular respiration uses O2 during its process. It can be seen in the equation:
C6H12O6 + 6O2 → 6CO2 + 6H2O
The process uses sugar molecule and six oxygen molecules to yield six carbon dioxide molecules and six water molecules. It is the direct opposite of photosynthesis, which has the chemical equation:
6CO2 + 6H2O → C6H12O6 + 6O2
Photosynthesis involves the used of six carbon dioxide molecules, six water molecules, and sunlight to yield sugar molecules, and six oxygen molecules.
