It is the conversion of CO2 into organic compounds and it forms 3-PGA.
Explanation:
Carbon fixation is one of the three stages in which the light independent phase of photosynthesis is divided into. It is the process whereby CO2, an inorganic source of carbon, is accepted by RUBP, leading to the formation of a 6-carbon compound that disintegrates into two 3-carbon molecules due to its instability.
The 3-carbon compounds are 3-phosphoglycerate or commonly known as 3-PGA. The carbon fixation stage is followed by reduction stage.
