WebApr 13, 2012 · CO 2 is absorbed via stomata, and O 2 is released by the same stomata. In CAM photosynthesis, or Crassulacean-Acid metabolism, the plant opens the stomata at night to minimize water loss in desert conditions. CO 2 is acquired at this time, and stored in vacuoles as malate. WebThe carbon-fixation pathway begins in the mesophyll cells, where carbon dioxide is converted into bicarbonate, which is then added to the three-carbon acid phosphoenolpyruvate (PEP) by an enzyme called phosphoenolpyruvate carboxylase.
