Q42. The oxygenation activity of RuBisCo enzyme in photorespiration leads to the formation of

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

Oxidation of ribulose‐1,5‐bisphosphate by Rubisco produces a 3‐carbon compound, 3‐phosphoglycerate, and a 2‐carbon compound, phosphoglycolate. Because carbon is oxidized, the process is termed photorespiration.
