plants such as maize whose vascular tissues are surrounded by two distinctive photosynthetic cell types In this anatomical context, the transport of CO2 from the external atmosphere to the bundle sheath cells proceeds through five successive stages such as;
a.) Fixation of the HCO3 − in phosphoenolpyruvate by PEP Case in the bundle sheath cells
b.) Transport of the four-carbon acids (malate or aspartate) to mesophyll cells that surround the vascular bundles
c.) Decarboxylation of the four-carbon acids and generation of CO2 which is then reduced to carbohydrate via the Calvin–Benson cycle
d.) Transport of the three-carbon backbone (pyruvate or alanine) formed by the decarboxylation step back to the mesophyll cells
e.) Regeneration of phosphoenolpyruvate, the HCO3 – acceptor
