Question

The  oxygenation activity of RuBisCo enzyme in photorespiration leads to the formation of :

(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 3-C compound and 1 molecule of 2-C compound

Answer 1

Ans : (4) 1 molecule of 3-C compound and 1 molecule of 2-C compound

Explanation :

The oxygenation activity of RuBisCo enzyme in photorespiration leads to the formation of 1 molecule of 3-phosphoglyceric acid (3-C compound) and 1 molecule of phosphoglycolate (2-C compound)
