A) stroma of chloroplasts and mitochondria
B) stroma of chloroplasts and peroxisomes
C) grana of chloroplasts and peroxisomes
D) stroma of chloroplasts
Correct Answer: B
Solution :
The first reaction of photorespiration occur in stroma of chloroplast. In this reaction the RuBP (Ribulose 1-5 biphosphate) consume one oxygen molecule in presence of enzyme Rubisco. In peroxisome the glycolate transferred from chloroplast takes up \[{{\text{O}}_{\text{2}}}\] and formed the glyoxylate, whereas the \[{{\text{H}}_{\text{2}}}{{\text{O}}_{\text{2}}}\] release as byproduct.
