WebMay 20, 2024 · Hatch and Slack observed that the C4 pathway was associated with a doubling of the light-saturated rate of photosynthesis compared with that of C3 plants, and an absence of photorespiration in C4 plants. These observations focused on the heart of why C4 photosynthesis was so important and successful in nature. 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.
