|
|
Rubisco

Explanation:
Detailed explanation-1: -The enzyme ribulose bisphosphate carboxylase oxygenase or RuBisCO catalyse the carboxylation of RuBP. It is the first step of the Calvin cycle and the carbon fixation reaction into stable organic intermediate 3-phosphoglyceric acid or PGA.
Detailed explanation-2: -The enzyme that catalyzes this specific reaction is ribulose bisphosphate carboxylase (RuBisCO). RuBisCO is identified as the most abundant enzyme on earth, to date. RuBisCO is the first enzyme utilized in the process of carbon fixation and its enzymatic activity is highly regulated.
Detailed explanation-3: -The enzyme Rubisco catalyzes the first step of photosynthetic carbon fixation in plants and algae.
