WebJun 8, 2024 · The C4 pathway bears resemblance to CAM; both act to concentrate CO 2 around RuBisCO, thereby increasing its efficiency. CAM concentrates it temporally, providing CO 2 during the day and not at night, when respiration is the dominant reaction. WebMar 23, 2009 · In C4 plants, the Calvin cycle activity occurs primarily in the bundle sheath cells, whereas PSII activity occurs in the mesophyll cells. Chloroplasts - The chloroplasts of C4 are dimorphic. Bundle sheath cell (BSC) chloroplasts are agranal. Recall that PSII occurs in the appressed regions of the chloroplasts.
