C4 carbon fixation

C4 carbon fixation is one of three biochemical processes, along with C3 and CAM photosynthesis, that fixes carbon. It is named for the 4-carbon molecule of the first product of carbon fixation found in the small subset of plants that use the C4 process. This process is in contrast to the 3-carbon molecule products of C3 plants.
