If Rubisco or an enzyme like Rubisco never existed, there would be no exchange of gases so organisms would not have evolved and we would not exist. Suppose the following operations were performed on an empty stack: How does Rubisco work in the photosynthesis process? Robert Anasi tells his story not as a journalist on assignment but as a man in the midst of one of the great adventures of his life. It catalyses the first step of carbon fixation in the C3 pathway or Calvin cycle, i.e. RuBisCO also has an affinity for oxygen so it binds to some amount of O, Since the affinity of RuBisCO is much higher for CO. Under saturating light conditions at low levels of intercellular CO2, assimilation is limited by the quantity and activity of rubisco, the enzyme that is primarily responsible for capturing atmospheric carbon in the production of sugars. In the C4 pathway, the Clavin cycle occurs in the bundle sheath cells. RuBP stands for ribulose bisphosphate and is a 5 carbon compound involved in the Calvin cycle, which is part of the light independent reactions of photosynthesis. Rubisco catalyses the primary photosynthetic CO 2 reduction reaction, the fixation of atmospheric CO 2 to ribulose-1,5-bisphosphate (RuBP) to form two molecules of 3-phosphoglycerate (3PGA), which is subsequently used to build the organic molecules of life. Rubisco activase attaches to thylakoid and this changes tertiary structure of enzyme. RuBisCO catalyses the first step of carbon fixation in the Calvin cycle.
