C3 photosynthesis

C3 photosynthesis is the major of the three metabolic pathways for carbon fixation by plants. This process uses the enzyme RuBisCO in relatively inefficient conditions, to fix CO2 from the air and obtain the 3-carbon organic intermediate molecule 3-phosphoglycerate. C3 photosynthetic plants possess a specific leaf structure, and are not adapted to non-optimal conditions.
