The First reaction in photorespiration is
Options
(a) carboxylation
(b) oxygenation
(c) decarboxylation
(d) phosphorylation
Correct Answer:
oxygenation
Explanation:
While doing studies on plant productivity it was found that a considerable proportion of the photosynthetic products was being oxidised to CO₂ and water without the production of metabolically useful energy. This was traced to a type of respiration which occurs in small organelles called peroxisomes, and because it occurs only in llight is called photorespiration. Under conditions of low CO₂ and high O₂ concentration which are normal atmospheric conditions, as much as 30-50% of the photosynthetically fix
