Q73
Which one is product in respiration and reagent in photosynthesis
A.
O2
B.
CO2
AnswerC.
CO
D.
N2
Answer: Option B
Solution
Answer: Option B
Solution:
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.
