NEET 2026 Biology question
Which of the following statements regarding photorespiration are correct? (a) Do not occur in C3 plants (b) CO is consumed and O is generated (c) Phosphoglycolate is formed (d) No synthesis of ATP and NADPH Choose the correct answer from the options given below:
Answer: (2)
Solution
Photorespiration occurs when RuBisCO acts as an oxygenase: RuBP + O gives one molecule of phosphoglycerate and one of phosphoglycolate (so (c) is correct). The pathway runs through chloroplast, peroxisome and mitochondrion; unlike photosynthesis or respiration there is no synthesis of ATP or
