Trace the path of a labeled carbon atom through the biological processes of photosynthesis and respiration. The atom will start

its journey inside a carbon dioxide molecule and it will end in the air inside a new carbon dioxide molecule. Your mission is to use your knowledge of photosynthesis and respiration to explain what happens to the carbon atom in these processes.

Cellular respiration and photosynthesis are reverse and complement reactions to each other.

In photosynthesis, carbon dioxide and water yield glucose and oxygen:
CO₂ + H₂O → C₆H₁₂O₆ + O₂

In the opposite reaction - cellular respiration, glucose and oxygen yield water and carbon dioxide:
C₆H₁₂O₆ + O₂ → CO₂ + H₂O
