Following are certain statements regarding Crassulacean Acid Metabolism (CAM) plants:
A. The HCO3- concentration is enriched in the cytosol during night by the CO2 coming from the external atmosphere through the open stomata and the mitochondrial respiration.
B. Oxaloacetate produced by the action of PEPCase is stored in the vacuole during dark.
C. During light, oxaloacetate produces malate that provides CO2 for Calvin Benson cycle in the chloroplast.
D. During dark, phosphoenolpyruvate is produced by the breakdown of starch present in the chloroplast.
E. CAM is a mechanism of concentrating CO2 around Rubisco by keeping stomata closed during day.
