CAM photosynthesis at night,illustration
CAM photosynthesis at night. Illustration of the night-time part of the mechanism involved in CAM (crassulacean acid metabolism) photosynthesis,used by some plants to obtain energy from sunlight. CAM plants open their gas-exchange pores (stomata) at night,as shown here. Carbon from carbon dioxide (CO2) is fixed by reactions involving the PEP (phosphoenolpyruvate) carboxylase enzyme,oxaloecetate,malate,and malic acid. The 4-carbon compound produced is stored in the mesophyll cell's vacuole (yellow) to be used in the day in the chloroplast (green). For the daytime reaction,see image C023/8824. For this artwork with labels,see C023/8821
