Find out and make a list of proteins used as therapeutic agents. Find other applications of proteins (e.g., Cosmetics etc.)
Match the following proteins/molecules in Column I with their primary function or characteristic in Column II. Column I (Protein/Molecule) (i) Collagen (ii) RuBisCO (iii) Insulin (iv) Trypsin (v) GLUT-4 (vi) Antibody Column II (Function/Characteristic) (1) Most abundant protein in the animal world (2) Most abundant protein in the whole biosphere (3) Functions as a hormone (4) Functions as an enzyme in digestion (5) Enables glucose transport into cells (6) Fights infectious agents
Correct answer: A — (i)-(1), (ii)-(2), (iii)-(3), (iv)-(4), (v)-(5), (vi)-(6)
This question tests the knowledge of specific examples of proteins and their diverse functions and abundances, as detailed in the NCERT text and Table 9.5. (i) Collagen matches (1): Collagen is listed as the most abundant protein in the animal world. (NCERT Page 110, Para 1). (ii) RuBisCO matches (2): Ribulose bisphosphate Carboxylase-Oxygenase (RuBisCO) is identified as the most abundant protein in the whole biosphere. (NCERT Page 110, Para 1). (iii) Insulin matches (3): Insulin is explicitly mentioned as a hormone. (NCERT Table 9.5). (iv) Trypsin matches (4): Trypsin is an enzyme. While not explicitly stated as 'in digestion' in the table, it is a well-known digestive enzyme, and its general classification as an enzyme is given. (NCERT Table 9.5). (v) GLUT-4 matches (5): GLUT-4's function is to enable glucose transport into cells. (NCERT Table 9.5). (vi) Antibody matches (6): Antibodies are known to fight infectious agents. (NCERT Table 9.5). All the pairs are correctly matched in option A. This question ensures recall of specific protein functions and their significance.
