The answer is:
Photosynthesis: 6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
Respiration: C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + ATP
Cellular respiration and photosynthesis are
complement reactions to each other. These are reverse reactions. In
cellular respiration glucose (C₆H₁₂O₆) and oxygen (O₂) yield carbon dioxide (CO₂) and water (H₂O) and energy is released in the form of ATP. In the opposite
reaction - in photosynthesis, carbon dioxide (CO₂) and water (H₂O) yield glucose (C₆H₁₂O₆) and
oxygen (O₂).
