Detailed explanation-1: -This reaction is catalyzed by the enzyme RuBP carboxylase/oxygenase, or rubisco. Reduction. In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into molecules of a three-carbon sugar, glyceraldehyde-3-phosphate (G3P).
Detailed explanation-2: -RuBisCO is thought to be the most abundant protein in the world since it is present in every plant that undergoes photosynthesis and molecular synthesis through the Calvin cycle.
Detailed explanation-3: -Using the energy carriers formed in the first stage of photosynthesis, the Calvin cycle reactions fix CO2 from the environment to build carbohydrate molecules. An enzyme, RuBisCO, catalyzes the fixation reaction, by combining CO2 with RuBP.
Detailed explanation-4: -Ribulose-1, 5-bisphosphate carboxylase/oxygenase, better known by the name Rubisco, is the key enzyme responsible for photosynthetic and chemoautotrophic carbon fixation and oxygen metabolism.
Detailed explanation-5: -1.1 Calvin cycle enzymes. Calvin cycle is operated by 11 different enzymes that catalyze 13 reactions. The “key” regulatory enzymes are RuBisCO, FBPase, SBPase, and PRK. These enzymes play a major role as they control the rate of CO2 fixation.
