Question
Which of the following statement is incorrect?
- Photorespiration occurs in chloroplasts
- Photorespiration occurs during day time
- Photorespiration occurs in C3 plants
- Photorespiration occurs in CAM plants
Hint:
Photorespiration refers to a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis
The correct answer is: Photorespiration occurs in CAM plants
- Photorespiration refers to a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis
- Photorespiration does not occur in CAM plants because these plants have evolve a better adaptation mechanism that is why they avoid photorespiration; they use PEP Caeboxylase instead of RUBISCO for the absorption of CO2 and in cam plants carbon fixation and calvin cycle both process occur at differnt time
- So answer is option 4
