WebAs mentioned earlier, the dark reaction is the actual phase where food is synthesized by the plants and it uses the energy generated by the light reactions. Phases of Dark Reaction Carbon Fixation: The CO2 taken in by the plant combines a 5 carbon compound known as ribulose 1,5- biphosphate to form two molecules of 3-phosphoglycerate(3PGA). WebThe light reaction is the first stage of photosynthesis, during which light energy is captured and used to produce ATP and NADPH, whereas the dark reaction is the second stage of …

WebThese reactions are also called the light-independent reactions because they are not directly driven by light. In the Calvin cycle, carbon atoms from \text {CO}_2 CO2 are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on, ATP and NADPH from the light reactions. helitape
