Sugarcane shows high efficiency of CO2 fixation because of
A metabolic pathway first defined by M.D. Hatch and C.R. Slack in 1966 to reduce photorespiration. In this pathway, the CO2 is first added to phosphoenolpyruvate by the enzyme PEP carboxylase, producing the four carbon compound in mesophyll cells, that is later transported to bundle sheath cells to liberate the CO2 for use in the Calvin cycle.
