In photorespiration, glycolate is converted into serine and carbon dioxide in:

1. Mitochondria

2. Cholorplasts

3. Vacuoles

4. Peroxisomes

The correct sequence of cell organelles during photorespiration is 

(1) chloroplast-Golgi bodies-mitochondria

(2) chloroplast-rough endoplasmic reticulum-dictyosomes

(3) chloroplast-peroxisome-mitochondria

(4) chloroplast-vacuole-peroxisome

During photorespiration, the oxygen consuming reaction(s) occur in :

(1) stroma of chloroplasts and mitochondria

(2) stroma of chloroplasts and peroxisomes

(3) grana of chloroplasts and peroxisomes

(4) stroma of chloroplasts

Photorespiration is favoured by

(1) high O₂ and low CO₂ concentration

(2) low O₂ and high CO₂ concentration

(3) low light intensity

(4) low temperature.

Photorespiration, usually occurs in

(1) one cell organelle

(2) two cell organelles

(3) three cell organelles

(4) four cell organelles.

The photorespiratory carbon-oxidation cycle involves the interaction of

1. chloroplast

2. mitochordria

3. peroxisomes

4. all of these.

Photorespiration in C₃ plants starts from:

(1) phosphoglycerate

(2) phosphoglycolate

(3) Glycerate

(4) glycine.
