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.

Carbon fixation is the conversion of CO2 into organic compounds, and it forms 3-PGA.

Hope this helped :)

Answer;

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

Explanation;Photosynthesis is the process by which green plants make their own food using energy from sunlight, together with carbon dioxide and water.Photosynthesis occurs in tow phases, the light-dependent stage and the light-independent stage. Carbon fixation occurs in the light independent stage or reactions of photosynthesis where inorganic carbon or carbon dioxide is converted to organic compounds. Carbon fixation is the first step in the C3 or calvin cycle. The calvin cycle converts carbon dioxide and water into organic compounds that can be used by organisms.
