Photorespiration could easily be detected in

Options

(a) C₃ plants
(b) C₄ plants
(c) Both C₃ plants & C₄ plants
(d) C₁ plant

Correct Answer:

C₃ plants

Explanation:

Fairly good amount of photosynthetic products get oxidised to CO₂ & H₂O without the production of useful energy in C₃ plants. This respiration takes place in chloroplast, peroxisomes and mitochondria and because it occur in light, so known as photorespiration. The energy released is lost as heat. The loss of carbon is due to dual activity of the enzyme RuBp carboxylase which can act not only as a carboxylase (useful role in Calvin cycle) but also as an oxygenase i.e. an enzyme which catalyzes the direct
