They combine CO 2 with a three-carbon compound in the mesophyll cells to form a four-carbon compound that passes into the bundle-sheath cells, where the CO 2 is regenerated. Therefore, Kranz plants can maintain a CO 2 level in the bundle-sheath cells that allows carboxylation of RuDP in the Calvin cycle to predominate over its oxidation in photorespiration. 31.
