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. WebAug 2, 2024 · In this pathway first, the stable product is a 4-carbon compound Oxaloacetic acid (AAO) , so-called a C4 pathway. Plants have Kranz Anatomy (vascular bundles are surrounded by bundle sheath cells arranged in a wreath-like manner), characterized by large no of a chloroplast, thick wall impervious to gases, and absence of intercellular spaces.
