Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Photorespiration pathway:
Chloroplast:
RuBisCO oxygenates RuBP → phosphoglycolate
Phosphoglycolate → glycolate
Peroxisome:
Glycolate → glyoxylate
Mitochondria: Glyoxylate → glycine
Chloroplast:
RuBisCO oxygenates RuBP → phosphoglycolate
Phosphoglycolate → glycolate
Peroxisome:
Glycolate → glyoxylate
Mitochondria: Glyoxylate → glycine
