Question

Assertion : Photorespiration is a wasteful process.\ Reason : In photorespiratory pathway, there is no synthesis of sugars or ATP.\

Professor PC Thomas Classes · Answer

(a) : Photorespiration is the light dependent process of oxygenation of ribulose bisphosphate (RuBP). In the photorespiratory pathway, there is neither synthesis of sugars nor of ATP. Rather, it results in the release of $\mathrm{CO}_{2}$ with the utilisation of ATP. Therefore, photorespiration is a wasteful process.
