Question

Match the following:
 

List I	Description	List II	Description
A	Glycosidic bond	I	Formed by dehydration
B	Hollow woollen ball folding	III	Tertiary structure of protein
C	Enzyme	II	Trypsin
D	Ester bond	IV	Bond between phosphate and 5th carbon of sugar

• A. A-II, B-I, C-IV, D-III
• B. A-IV, B-III, C-I, D-II
• C. A-III, B-II, C-I, D-IV
• D. A-IV, B-I, C-II, D-III

Hint:

Protein tertiary structure resembles a coiled mass. Trypsin is a protease. Glycosidic and ester bonds are dehydration linkages in biomolecules.

Answer 1

The Correct Option is B

Step 1: A - Glycosidic bond → IV
A glycosidic bond forms between two monosaccharides through a dehydration reaction (loss of water molecule).
→ A matches with IV.

Step 2: B - Hollow woollen ball folding → III
This is a descriptive analogy for the complex three-dimensional (tertiary) folding of a protein.
→ B matches with III.

Step 3: C - Enzyme → I
Trypsin is a well-known proteolytic enzyme, responsible for breaking peptide bonds in proteins.
→ C matches with I.

Step 4: D - Ester bond → II
In nucleotides, ester bonds form between the phosphate group and the 5^th carbon of the sugar molecule.
→ D matches with II.
