Catalysis enhances the Calvin Cycle by significantly increasing the rate at which the biochemical reactions occur. For example, RuBisCO, despite being the most abundant enzyme on Earth, is relatively slow. However, it is highly efficient in catalyzing the reaction between carbon dioxide and ribulose-1,5-bisphosphate. Enzymatic catalysis ensures that even minor concentrations of reactants are converted into products swiftly, thus maintaining the cycle's efficiency.
