NEET Zoology (general) MCQ Question
Which combination of statements about biomolecules is correct?
Collagen is a protein and RuBisCO is the most abundant protein in the biosphere.
Cellulose is a heteropolymer consisting of multiple types of monosaccharides.
Polysaccharides are short chains of sugars, typically less than ten monomers long.
Starch serves as a storage form of energy in plants, while cellulose provides structural support.
Correct Answer
Detailed Explanation
Collagen is indeed a protein, and RuBisCO is noted as the most abundant protein in the biosphere. Cellulose is a homopolymer made solely of glucose, not a heteropolymer, making option B incorrect. Polysaccharides typically consist of long chains of sugars, rather than short chains, as stated in option C. Option D is partially correct but does not explicitly mention that cellulose is a homopolymer, which is a key detail.
