Answer:
carbon dioxide, water, ATP
Explanation:
the equations for photosynthesis and cellular respiration are exact opposites. The reactants for photosynthesis are the products for respiration.
photosynthesis:
6CO₂ + 6H₂O + ATP (energy) ---> C₆H₁₂O₆ + 6O₂
respiration:
C₆H₁₂O₆ + 6O₂ ---> 6CO₂ + 6H₂O + ATP
