The reaction of carbon dioxide and RUBP is catalyzed by?

Explanation

The reaction between carbon dioxide (CO2) and ribulose-1,5-bisphosphate (RuBP) is catalyzed by the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase, commonly known as Rubisco. This reaction is a crucial step in the Calvin cycle, which is the light-independent phase of photosynthesis responsible for the fixation of carbon dioxide and the synthesis of carbohydrates. Rubisco adds carbon dioxide to RuBP, leading to the formation of an unstable six-carbon compound that immediately splits into two molecules of 3-phosphoglycerate (3-PGA).
