Photorespiration occurs when the enzyme acts as an oxygenase. What are the final products of this process in the chloroplast?
- A.One molecule of and one molecule of
- B.Two molecules of
- C.Two molecules of
- D.One molecule of and one molecule of
Show correct answer & step-by-step solution
Correct answer: A — One molecule of and one molecule of
Solution
- RuBisCO reacts with instead of during photorespiration.
- The substrate Ribulose 1,5-bisphosphate is cleaved into two fragments.
- The products are one molecule of 3-phosphoglycerate (3C) and one molecule of phosphoglycolate (2C).
- Hence the answer is (A).
