C4 carbon fixation or the Hatch–Slack pathway is one of three known photosynthetic processes of carbon fixation in plants. It owes the names to the 1960's discovery by Marshall Davidson Hatch and Charles Roger Slack that some plants, when supplied with CO2, incorporate the C label into four-carbon molecules first. … See more The first experiments indicating that some plants do not use C3 carbon fixation but instead produce malate and aspartate in the first step of carbon fixation were done in the 1950s and early 1960s by Hugo Peter Kortschak and … See more In C3 plants, the first step in the light-independent reactions of photosynthesis is the fixation of CO2 by the enzyme RuBisCO to form 3-phosphoglycerate.
