Photorespiration:

Question

Photorespiration: (A) occurs because oxygen rather than carbon dioxide links to the RuBisCO enzyme in the Calvin cycle. (B) occurs more in C 4 than in C 3 plants under identical conditions. (C) describes the uptake of CO 2 the release of oxygen in chloroplasts. (D) All of the above

Light induced CO 2 liberation from a C 2 compound (glycolic acid) of dark phase is called photorespiration. It occurs in green cells only. It is absent in C 4 plants and present in C 3 plants. Photorespiration occurs because oxygen rather than carbon dioxide links to the rubisco enzyme in the Calvin cycle. It involves three cell organelles - peroxisomes, chloroplast and mitochondria.

Q. Photorespiration:

occurs because oxygen rather than carbon dioxide links to the RuBisCO enzyme in the Calvin cycle.

occurs more in $C_{4}$ than in $C_{3}$ plants under identical conditions.

describes the uptake of $C O_{2} &$ the release of oxygen in chloroplasts.

All of the above
