C3 carbon fixation is a metabolic pathway for carbon fixation in photosynthesis. This process converts carbon dioxide and ribulose bisphosphate(RuBP, a 5-carbon sugar) into 3-phosphoglycerate. This reaction occurs in all plants as the first step of the Calvin-Benson cycle. Plants that survive solely on C3 fixation tend to thrive in areas where sunlight intensity is moderate, temperatures are moderate, carbon dioxide concentrations are around 200 ppm or higher, and ground water is plentiful.
