 Fractionation of carbon isotopes in oxygenic photosynthesis

Fractionation of carbon isotopes in oxygenic photosynthesis refers to the differential uptake and incorporation of carbon isotopes (\(^{12}C\) and \(^{13}C\)) by photosynthetic organisms, primarily plants and cyanobacteria, during the process of converting carbon dioxide (CO2) into organic carbon compounds using sunlight.
