Question

In photorespiration, glycolate and glyoxylate are produced sequentially in the following organelles:

• A. Chloroplasts and Mitochondria
• B. Chloroplasts and Peroxisome
• C. Peroxisome and Mitochondria
• D. Peroxisome and Chloroplast

Hint:

Photorespiration can reduce C3 plant photosynthesis efficiency by up to 25% on hot days.

Answer 1

The Correct Option is B

Photorespiration pathway:
Chloroplast:
RuBisCO oxygenates RuBP → phosphoglycolate
Phosphoglycolate → glycolate
Peroxisome:
Glycolate → glyoxylate
Mitochondria: Glyoxylate → glycine
