    • CAM (Crassulacean Acid Metabolism) plants are found in xerophytic conditions.
    • CAM pathway is exhibited by crassulaceae, euphorbiaceae, cactaceae etc. 
    • Their stomata open only during the night, fixing carbon onto different compounds and then releasing the fixed carbon into the C3 cycle during the day when plants perform photosynthesis.
    • The CO2 taken up by succulent plants at night is fixed in a similar way as it takes place in C4 plants to form malic acid, which is being stored in vacuole.
    • These acids are decarboxylated and the CO2 released is fixed to produce PGA.
