Which protein found in maximum amount?
aCatalase
bZinc carbonic anhydrase
cTransferase
dRuBisCO
✓ Correct answer: d) RuBisCO
ExplanationRuBisCO (Ribulose-1,5-bisphosphate carboxylase/oxygenase) is widely considered the most abundant protein on Earth (in the biosphere).It is a critical enzyme involved in the first major step of carbon fixation during photosynthesis in plants, algae, and cyanobacteria, converting atmospheric carbon dioxide into organic molecules.Its essential role in sustaining life and the vast amount of plant biomass on the planet means it is produced in large quantities, making up a significant percentage (up to 50%) of total soluble protein in plant leaves.A. Catalase: Catalase is a highly efficient enzyme that breaks down hydrogen peroxide, protecting cells from damage, and is found in most living organisms.B. Zinc carbonic anhydrase: Carbonic anhydrase is a very fast-acting enzyme vital for maintaining acid-base balance and transporting carbon dioxide in biological systems.C. Transferase: Transferases are a class of enzymes that catalyze the transfer of functional groups between molecules and are involved in many biochemical pathways.This is a general class of enzymes.
