During phase 1 of this cycle, the CO2 molecule is incorporated into one of two 3-phosphoglycerate molecules (3-PGA). This process requires the enzyme RuBisCO and both ATP and NADPH. Once 3-PGA is formed, one of two molecules formed continues into the reduction phase (phase 2). The additional 3-PGA is utilized in additional metabolic pathways such as glycolysis and gluconeogenesis. The structure of 3-PGA allows it to be combined and rearranged to form sugars which can be transported to additional cells or stored for energy.
