Carbon fixation and G3P synthesis The Calvin cycle starts by using the enzyme Rubisco to fix CO 2 into five-carbon Ribulose bisphosphate (RuBP) molecules. Source: Internet
Carbon fixation is an endothermic redox reaction, so photosynthesis needs to supply both a source of energy to drive this process, and the electrons needed to convert carbon dioxide into a carbohydrate via a reduction reaction. Source: Internet
