Why does Photorespiration not Occur in CAM Plants?
Why Photorespiration Does Not Occur in CAM Plants?
CAM plants avoid photorespiration because they use PEP carboxylase instead of RUBISCO to absorb carbon dioxide. CAM plants open their stomata at night and incorporate CO2 into organic acids, preventing photorespiration.
Do CAM Plants Use RuBisCO?
Yes, CAM plants use RuBisCO. RuBisCO, or rubisco, is a key enzyme in photosynthesis.
Which Cycle Lacks Photorespiration?
The C4 cycle avoids photorespiration. C4 plants, such as sugarcane, maize, and sorghum, use the PEP enzyme during the first step of carbon fixation to avoid photorespiration.
How is Photorespiration Avoided in CAM Plants?
CAM plants avoid photorespiration by separating initial fixation and the Calvin cycle in space, performing these steps in different cell types.
Why do CAM Plants Grow Slowly?
CAM plants grow slowly because of their low photosynthetic capacity, which is limited by vacuolar storage capacity and ATP costs.
Why does Photorespiration not occur in CAM Plants?
Why does Photorespiration not occur in CAM Plants?: A CAM (Crassulacean acid metabolism) plant is a type of plant that fixes carbon dioxide through the CAM pathway, which evolved in some plants to adapt to arid conditions. Let’s read why does photorespiration not occur in CAM plants.
