Question

write a brief note on photo respiration?​

Answer 1

Answer:

Photorespiration is the process where the enzyme RuBisCO oxygenates RuBP with the release of carbon dioxide. It is also known as a wasteful process because it prevents the plant from using ATP and NADPH to synthesize carbohydrate. It occurs in C3 plants and not in C4 plants.

Answer 2

Photorespiration is the process of light-dependent uptake of molecular oxygen (O2) concomitant with release of carbon dioxide (CO2) from organic compounds. The gas exchange resembles respiration and is the reverse of photosynthesis where CO2 is fixed and O2 released .
