Biology Question on Photosynthesis in higher plants
During photorespiration, the oxygen consuming reaction(s) occur in:
A
stroma of chloroplasts and mitochondria
B
stroma of chloroplasts and peroxisomes
C
grana of chloroplasts and peroxisomes
D
stroma of chloroplasts
Answer
stroma of chloroplasts and peroxisomes
Explanation
Solution
Photorespiration primarily takes place in the chloroplasts and peroxisomes of plant cells. In the chloroplasts, it involves the oxygenase activity of ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO), and in the peroxisomes, the glycolate pathway is involved in processing the products of oxygenation.
So, the correct option is (B): stroma of chloroplasts and peroxisomes
