WebCAM plants are succulents and grow in dry regions. Due to excessive heat the stomata remains closed during the day to reduce transpiration. Their stomata opens at night. at night stomata are open by PEPA and OAA in the presence of PEPAcarboxylase. WebThe mechanism of photosynthesis in C4 plants was elucidated in the 1960 s by Hatch and Slack in Australia. C4 plants are so-called because the first product of CO2 fixation is a C4 organic acid, oxaloacetate, formed by the carboxylation of phosphoenolpyruvate (PEP) by PEP carboxylase.

WebPGA is a three-carbon compound, and the mode of photosynthesis is thus referred to as C 3. In the two other known pathways, C 4 and CAM (crassulacean acid metabolism), the C 3 pathway follows the fixation of CO 2 into oxaloacetate, a four-carbon acid, and its reduction to malate. PGA is formed from 2-carboxy-3-keto-D-arabinitol 1,5-bisphosphate ...
