Which of the following chemical reactions proves the fact that the products of photosynthesis are reactants of respiration?
AlladinOne [14]
<span>The answer is:
Photosynthesis: 6 CO</span>₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
Respiration: C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + ATP<span>

Cellular respiration and photosynthesis are complement reactions to each other. These are reverse reactions. In cellular respiration glucose (</span>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 (<span>O₂)</span><span>. </span>
