NEET · BiologyHard
Which of the following statements accurately describes the role of the oxygenase activity of in photorespiration?
- A.It produces one molecule of and one molecule of phosphoglycolate.
- B.It consumes to convert glycolate into glyoxylate in the peroxisome.
- C.It releases in the chloroplast during the conversion of glycine to serine.
- D.It is a beneficial process that increases the net carbon gain of the plant.
Show correct answer & step-by-step solution
Correct answer: A — It produces one molecule of and one molecule of phosphoglycolate.
Solution
- catalyzes the reaction of with instead of .
- The reaction products are one molecule of () and one molecule of .
- This initiates the photorespiratory pathway.
- Hence the answer is (A).
