Final answer:
RuBisCO, abbreviated for ribulose 1,5-bisphosphate carboxylase/oxygenase, plays a key role in carbon fixation during photosynthesis. It catalyzes the reaction between CO₂ and RuBP, producing 3-phosphoglycerate (3-PGA) and enabling the regeneration of RuBP. RuBisCO does not produce ATP or break down glucose.
Step-by-step explanation:
RuBisCO, abbreviated for ribulose 1,5-bisphosphate carboxylase/oxygenase, plays a key role in photosynthesis by catalyzing the reaction between carbon dioxide (CO₂) and ribulose bisphosphate (RuBP). This process, known as carbon fixation, results in the production of 3-phosphoglycerate (3-PGA). Additionally, RuBisCO also helps in the regeneration of RuBP, enabling the continuous fixation of CO₂ in the Calvin cycle. It does not produce ATP, break down glucose, or convert glucose to pyruvate.
The role of ribulose 1,5-bisphosphate carboxylase/oxygenase, abbreviated as RuBisCO, in photosynthesis is to catalyze a key reaction in the Calvin cycle. Specifically, RuBisCO facilitates the carbon fixation process by catalyzing the reaction between carbon dioxide (CO2) and ribulose bisphosphate (RuBP) to produce 3-phosphoglycerate (3-PGA), which is then used to form glucose and regenerate RuBP.
