Q.
The oxygenation activity of RuBisCO enzyme in photorespiration leads to the formation of [2020]

1 2 molecules of 3-C compound

2 1 molecule of 3-C compound

3 1 molecule of 6-C compound

4 1 molecule of 4-C compound and 1 molecule of 2-C compound

Ans.
(2)

During photorespiration in $C_{3}$ plants, some $O_{2}$ does bind to RuBisCO and RuBP instead of being converted to 2 molecules of PGA. It binds with $O_{2}$ to form one molecule of phosphoglycerate (3 Carbon) and phosphoglycolate (2 Carbon).
