Read the following descriptions of biomolecules: (i) A secondary metabolite categorised as an alkaloid. (ii) A protein that functions as a hormone. (iii) A protein that acts as an intercellular ground substance. Choose the option that correctly identifies these biomolecules in the given order.

Step-by-step solution

Based on the NCERT classifications of biomolecules: (i) Alkaloids are secondary metabolites that include morphine and codeine. Ricin and abrin are categorised as toxins. (ii) Insulin is a protein that functions as a hormone, whereas trypsin is an enzyme. (iii) Collagen is a protein that acts as an intercellular ground substance. Cellulose and chitin are structural polysaccharides, not proteins. Therefore, the correct sequence matching the descriptions is Codeine, Insulin, and Collagen. Answer: Codeine, Insulin, Col
