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

Step 1: Glycolate is formed in the chloroplast from phosphoglycolate.
Step 2: Glycolate moves to the peroxisome and is oxidised to glyoxylate.
Step 3: Mitochondria act only later, converting glycine, not glycolate or glyoxylate.
Step 4: Correct answer, Chloroplasts and Peroxisome.
