What is carbon fixation, and how does it relate to photosynthesis?

It is the absorption of CO2 from the air, and it occurs during the light-dependent reactions.
It is the reduction of CO2, and it occurs during the Calvin cycle.
It is the conversion of CO2 into organic compounds, and it forms 3-PGA.
It is the production of CO2 during regeneration, and it forms RuBP.

Answer:

It is the conversion of CO2 into organic compounds and it forms 3-PGA.

Step-by-step 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.
