Which one is product in respiration and reagent in photosynthesis

Solution(By Examveda Team)

CO₂ is one product in respiration and a reagent in photosynthesis.
Cellular respiration converts ingested nutrients in the form of glucose (C₆H₁₂O₆) and oxygen to energy in the form of adenosine triphosphate (ATP). CO₂ is produced as a byproduct of this reaction.
During photosynthesis, plants take in carbon dioxide (CO₂) and water (H₂O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons.
