NEETBotanyBiomolecules (B)
Which of the following options correctly pairs a biomolecule with its chemical nature and its specific function or characteristic?
Options
- ARuBisCO – Protein – Intercellular ground substance
- BConcanavalin A – Secondary metabolite – Toxin
- CGLUT-4 – Lipid – Enables glucose transport into cells
- DTrypsin – Protein – Enzyme
Correct answer
D. Trypsin – Protein – Enzyme
Step-by-step solution
Trypsin is a protein that functions as an enzyme. RuBisCO is a protein but it acts as an enzyme, whereas collagen acts as intercellular ground substance. Concanavalin A is a secondary metabolite but it is categorized as a lectin, not a toxin (abrin and ricin are toxins). GLUT-4 enables glucose transport into cells, but it is a protein, not a lipid. Answer: Trypsin – Protein – Enzyme
