Crassulacean Acid Metabolic Cycle or CAM cycle is found in in plants of crassulaceae family eg Kalanchoe pinnate (bryophyllum) and euphorbiaceae family eg Euphorbia sp, codiaeum variegatum etc.
Photorespiration:
Photo respiration occurs in C3 plants. In C3 cycle, rubisco enzyme binds with carbon dioxide and and through the cycle it produces glucose. Some of the rubisco enzyme also binds with oxygen, if the amount of oxygen is high and temperature is high. Thus, the amount of glucose produced is less. Moreover, some of the glucose produced is also oxidized which causes further loss of glucose. This is called photo respiration because it is not the main respiration which takes place in mitochondria but another type of respiration which takes place in the presence of sunlight.
