Question
Carboxylation 
-cycle) is the fixation of 
into
- Amino acid
- Cholesterol ring
- Proteins
- Organic intermediate
The correct answer is: Organic intermediate
Carboxylation(In 
-cycle) It is the fixation of into a stable organic intermediate. Carboxylation is the most crucial step of the Calvin cycle, where is utilised for the carboxylation of RuBP. This reaction is catalysed by the enzyme RuBP carboxylase, which results in the formation of two molecules of 3-PGA. Since, this enzyme also has an oxygenation activity. It would be more correct to call it RuBPcarboxylase-oxygenaseor RuBisCo
