What is Photorespiration?
Photorespiration is a process in plant metabolism that involves the uptake of oxygen and the release of carbon dioxide from organic compounds. It is the reverse of photosynthesis, which fixes carbon dioxide and releases oxygen. Photorespiration occurs when the enzyme RuBisCO reacts with oxygen instead of carbon dioxide and this can happen on warm, arid days when plants close their stomata to prevent excess water loss. Photorespiration is harmful to C3 plants because it reduces plant productivity.
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.
