Q. In photorespiration, what is the role of peroxisome?

A) Helps in oxidation of glyocolate
B) Helps in oxygenation of glycolate
C) Helps in synthesis of PGA
D) Helps in reduction of glyoxylate
Explanation

The site for photorespiration is chloroplast. Peroxisome and mitochondria are required for completion of the process. It is a cyclic process. Glycolate is formed in chloroplast, which usually passes into peroxisome of the mesophyll cell where it is oxidised to glyoxylate. Glyoxylate is aminated and gives rise to amino acid glycine that enters to mitochondrion.
