RuBP + O2 ---Rubisco---> PGA + _ .
Correct answer: B. Phosphoglycolate
- A. Phosphoglycerate
- B. Phosphoglycolate
- C. Glycerate
- D. Glycolate
Explanation
When RuBP reacts with oxygen instead of CO₂ in a process called photorespiration, RuBisCO catalyzes the formation of one molecule of 3-phosphoglycerate (PGA) and one molecule of 2-phosphoglycolate (Phosphoglycolate). This process occurs when plants have less CO2 but high O2.
