BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The enzyme ribulose-1, 5-bisphosphate carboxylase/oxygenase, most commonly known by the shorter name RuBisCO or just rubisco is used in the Calvin cycle to catalyze the first major step of carbon fixation.

Detailed explanation-2: -RuBisCO: 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-3: -Ribulose 1, 5-bisphosphate carboxylase-oxygenase (RuBisCO) is the enzyme responsible for the fixation of carbon derived from atmospheric CO2 as part of the Calvin-Benson cycle that leads to production of the glucose essential for growth in most photosynthetic organisms.

Detailed explanation-4: -Rubisco catalyses the primary photosynthetic CO2 reduction reaction, the fixation of atmospheric CO2 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.

Detailed explanation-5: -The enzyme ribulose 1, 5-bisphosphate carboxylase (Rubisco) catalyses the entry of carbon dioxide into photosynthetic metabolism, provides acceptor molecules that consume the products of the light reactions of photosynthesis, and regulates the pool sizes of important photosynthetic intermediates.
