Carbon fixation occurs during the light independent … WebDec 24, 2024 · In fixation, the first stage of the Calvin cycle, light-independent reactions are initiated; CO 2 is fixed from an inorganic to an organic molecule. In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADP +, respectively. WebHere’s how all this works: PEP carboxylase is located in the mesophyll cells, on the leaf exterior near the stomata. There is no rubisco in the mesophyll cells. CO2 entering the stomata is rapidly fixed by PEP carboxylase into a 4-carbon compound, called malate, by attaching the CO2 to PEP. in daily over the counter iron supplements
