The process of photorespiration occurs in
Options
(a) all plants
(b) C₄ plants
(c) C₃ plants
(d) algae only
Correct Answer:
C₃ plants
Explanation:
Photorespiration takes place only in C₃ plants as at high temperature and high oxygen concentration RuBP carboxylase changes to RuBP oxygenase. Photorespiration is not present in C₄ plants because Rubisco and other Calvin cycle enzymes are present only in bundle sheath cells, and CO₂ concentration in those cells is maintained too high for O₂ to compete with CO₂, Temperature is also low in bundle sheath cells of C₄ plant.
