A) fix CO_2 into a four-carbon compound instead of a three-carbon compound

Some plants are called C4 plants because their first product of carbon fixation is a 4- carbon compound instead of a 3-carbon compound which is for most of the plants. These plant use this four carbon compound effectively to use them to concentrate CO_2 in the chloroplast (rubisco) so that the chloroplast is less likely to react with oxygen.
