Carbon fixation involves the addition of carbon dioxide to _____.
The correct answer is option D.
Carbon fixation involves the addition of carbon dioxide to RuBP.
In the Calvin cycle, carbon dioxide is added to RuBP.
The chemical name of RuBP is Ribulose 1, 5-bisphosphate. It is an organic substance that is involved in photosynthesis. It is a colorless anion with a double phosphate ester of the ketopentose called ribulose. The ketone of ketopentose contains sugar with carbon atoms. Salts of RuBP has an essential function in the solution.
The process in which organic compounds are formed from inorganic compounds or carbon dioxide by the living organisms. The inorganic compounds or carbon dioxide acts as a substrate in this process; therefore, it is called carbon fixation.
The organic compounds, which are the product of this process, helps in energy production and growth of autotrophs.
The process of carbon fixation is carried out in nutrients productive environment such as the marine environment. Also, the major part of this process happens in the plant system during photosynthesis which involves the RUBISCO protein.
Carbon dioxide in plants enters the interior of the leaf through pores which are called stomata.
This carbon dioxide diffuses in the stroma of the chloroplast where sugar is synthesized at the site of the Calvin cycle reaction.
In the Calvin cycle, carbon atoms from carbon dioxide are fixed and are used to form three-carbon sugars. This process is dependent on energy from ATP and NADPH of the light reactions.
