Although CAM plants stagger this process between night and day, most plants run it between the physically segregated mesophyll and sheath bundle cells.
Some unicellular diatoms can run this process in their cytosol, and cells specialized for this purpose have been discovered in the vascular tissue of tobacco. To avoid the oxygenase activity that leads to photorespiration, carbon dioxide combines with PEP to form the oxaloacetate that provides its name. Although CAM plants stagger this process between night and day, most plants run it between the physically segregated mesophyll and sheath bundle cells. FTP, what is this metabolic pathway preceding the Calvin-Benson cycle used by plants in arid environments to conserve water?
