WebbRuBP has five atoms of carbon and a phosphate group on each end. RuBisCO catalyzes a reaction between CO 2 and RuBP, which forms a six-carbon compound that is immediately converted into two three-carbon compounds. This process is called carbon fixation, because CO 2 is “fixed” from its inorganic form into organic molecules. WebbAn enzyme, RuBisCO, catalyzes the fixation reaction, by combining CO 2 with RuBP. The resulting six-carbon compound is broken down into two three-carbon compounds, and the energy in ATP and NADPH is used to convert these molecules into G3P. One of the three-carbon molecules of G3P leaves the cycle to become a part of a carbohydrate molecule.
