Question

Select the wrong statement from the following.

• A. Ribozymes are nucleic acids with catalytic power.
• B. Nucleic acids serve as genetic material.
• C. Proteins, nucleic acids and polysaccharides are the only three types of macromolecules found in the living system.
• D. Collagen is the most abundant protein in the whole of the biosphere and RuBisCo is the most abundant protein in the animal world.

Answer 1

Answer: (D)

-Collagen is the most abundant protein in the animal world and Ribulose bisphosphate carboxylase-oxygenase (RUBISCO) is the most abundant protein in the whole of the biosphere.
-Collagen is the most abundant protein in the human body
-Rubisco found in the stroma of chloroplast and has Bifunctional activity (carboxylase and oxygenase)
-Low CO₂ high O₂ → Rubisco perform oxygenase activity.
-High CO₂ low O₂ → Rubisco perform carboxylase activity
