• A. $a-3,b-4,c-2,d-1$
• B. $a-4,b-1,c-2,d-3$
• C. $a-2,b-4,c-1,d-3$
• D. $a-3,b-4,c-1,d-2$

Answer 1

Answer: (A)

$a-3,b-4,c-2,d-1$

Collagen is the most abundant protein in animals. It forms the intercellular ground substance in connective tissue tissue of animals. It is a white fibrous protein with very thin fibres which occur in bundles. It is flexible but inelastic.

Trypsin is an enzyme present in pancreatic juice and helps in the breakdown of proteins into peptides and petones. It is initially secreted in an inactive form called trypsinogen which is first activated into its active form trypsin by other enzyme enterokinase secreted by intestine. Insulin is hormone secreted by pancreas and helps in keeping the blood sugar level low. It makes the liver to store excess amount of glucose in the form of glycogen and also makes the cells to absorb glucose to produce energy. Glut-4 is an insulin regulated glucose transporter primarily found in adipose tissue and striated muscles. It lays a key role in maintaining whole body glucose homeostasis.

Thus, the correct answer is option A.
