NEETBotanyBiomolecules (B)
Select the incorrect match regarding the biomolecule, its biological function, and the type of bond linking its monomers:
Options
- AGLUT-4 Enables glucose transport into cells Glycosidic bond
- BCollagen Intercellular ground substance Peptide bond
- CTrypsin Enzyme Peptide bond
- DAntibody Fights infectious agents Peptide bond
Correct answer
A. GLUT-4 Enables glucose transport into cells Glycosidic bond
Step-by-step solution
According to NCERT, GLUT-4, collagen, trypsin, and antibodies are all proteins. Proteins are polypeptides, which are linear chains of amino acids linked by peptide bonds. GLUT-4 is a protein that enables glucose transport into cells. Since it is a protein, its monomers (amino acids) are linked by peptide bonds, not glycosidic bonds. Glycosidic bonds are characteristic of polysaccharides (carbohydrates). Therefore, the match for GLUT-4 is incorrect. Answer: GLUT-4 Enables glucose transport into cells Glycosidic bond
