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.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
