Question: 177: Match List-I with List-II
| List-I (Biological Molecules) | List-II (Biological functions) |
|---|---|
| (a) Glycogen | (i) Hormone |
| (b) Globulin | (ii) Biocatalyst |
| (c) Steroids | (iii) Antibody |
| (d) Thrombin | (iv) Storage product |
Choose the correct answer from the options given below:
(1) (a) – (ii), (b) – (iv), (c) – (iii), (d) – (i)
(2) (a) – (iv), (b) – (iii), (c) – (i), (d) – (ii)
(3) (a) – (iii), (b) – (ii), (c) – (iv), (d) – (i)
(4) (a) – (iv), (b) – (ii), (c) – (i), (d) – (iii)
Answer: Option (2)
Explanation:
Glycogen is a polysaccharide that serves as the main storage form of glucose in animals.
Therefore, Glycogen corresponds to the function storage product.
Globulins are proteins present in blood plasma, and immunoglobulins function as antibodies.
Hence, Globulin corresponds to antibody.
Steroids include hormones such as estrogen, testosterone and cortisol.
Thus, Steroids correspond to the function hormone.
Thrombin is an enzyme involved in blood clotting and catalyzes the conversion of fibrinogen to fibrin.
Therefore, Thrombin functions as a biocatalyst.
Hence, the correct matching is (a) – (iv), (b) – (iii), (c) – (i), (d) – (ii).
