CO2 Uptake in CAM Plants at Night
CO2 Uptake in CAM Plants at night take place in the following steps:
- CAM plants open stomata during the night and fiix atmospheric CO2 using PEP carboxylase enzyme. This enzyme has a higher affinity for CO2 than oxygen, reducing the chance of photorespiration.
- CO2 is fixed and converted into organic acids during the night which is then stored in vacuoles within plant cells until daylight.
- During the day, organic acids are broken down and releases CO2 for use in the Calvin cycle of photosynthesis.
- Stomata remain closed during the day to minimize water loss, preventing both water loss and photorespiration.

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.
