DENDROLOGY

Detailed explanation-1: -RuBisCO’s primary function is photosynthesis and photorespiration. It catalyzes the first step in the C3 pathway or Calvin cycle, namely the carboxylation of RuBP . It leads to the production of two 3-PGA molecules. RuBisCO also has an affinity for oxygen, thus it binds to some O2 during the photorespiration process.

Detailed explanation-2: -During the first phase of the Calvin cycle, carbon fixation occurs. The carbon dioxide is combined with ribulose 1, 5-bisphosphate to form two 3-phosphoglycerate molecules (3-PG). The enzyme that catalyzes this specific reaction is ribulose bisphosphate carboxylase (RuBisCO).

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: -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-5: -Rubisco is ubiquitus for photosynthetic organisms and is regarded as the most abundant protein on earth., From a nutritional point of view, the large subunit of Rubisco has an exceptionally ideal composition of essential amino acids among plant proteins.
