NEET BIOLOGY

Detailed explanation-1: -Ribulose-1, 5-bisphosphate carboxylase/oxygenase, better known by the name Rubisco, is the key enzyme responsible for photosynthetic and chemoautotrophic carbon fixation and oxygen metabolism.

Detailed explanation-2: -RuBisCo is the most abundant enzyme in nature and responsible for about 95% of the carbon fixed in the biosphere, but it is also very slow and unspecific.

Detailed explanation-3: -The enzyme Rubisco, short for ribulose-1, 5-bisphosphate carboxylase/oxygenase, is the enzyme that incorporates CO2 into plants during photosynthesis. As it constitutes about 30% of the total protein in a plant leaf, Rubisco is probably the most abundant protein on earth and a major sink for plant nitrogen.

Detailed explanation-4: -Ribulose-1, 5-bisphosphate carboxylase/oxygenase (RubisCO) is arguably one of the most abundant proteins in the biosphere and a key enzyme in the global carbon cycle.

Detailed explanation-5: -Rubisco takes carbon dioxide and attaches it to ribulose bisphosphate, a short sugar chain with five carbon atoms. Rubisco then clips the lengthened chain into two identical phosphoglycerate pieces, each with three carbon atoms.
