Answer:
Carbon fixation during photosynthesis
Step-by-step explanation:
Photosynthesis is the process through which plants synthesise carbohydrates using light energy from the sun. The overall equation is
CO2 + H20 + (energy) → glucose + oxygen
Photosynthesis can be split into two stages: The light-dependent reactions, and the light-independent reactions. Carbon fixation (sometimes called the Calvin cycle) is part of the light independent reactions
During carbon fixation, carbon dioxide is incorporated into a 5 carbon sugar called RuBP. This immediately forms two molecules of 3-PGA, which is converted into G3P. Some of the G3P is used to synthesise sugars, and the rest is used to regenerate RuBP.
