Detailed explanation-1: -CO2 combines with RuBP in the presence of enzyme RuBisCO to form 3-PGA.
Detailed explanation-2: -(a) An enzyme, RuBP carboxylase, catalyzes both the joining of carbon dioxide with RuBP and the joining of oxygen gas with RuBP. The two molecules are alternative substrates that compete with each other for the same active site on the enzyme.
Detailed explanation-3: -Carbon dioxide enters the cycle and is fixed by Rubisco to a 5-carbon sugar called ribulose biphosphate (RuBP), which is immediately broken down to form two 3-carbon molecules of phosphoglycerate (PGA).
Detailed explanation-4: -RuBP, which stands for ribulose bisphosphate, is a 5-carbon molecule that is involved in the Calvin cycle, which is one of the photosynthesis’s light-independent processes. With the aid of an enzyme called RuBisCO, atmospheric carbon dioxide is coupled with RuBP to generate a 6 carbon molecule.
