ii) Heterocyclic ring structure

iii) Hydrolase

iv) Haem

Chemical Composition of Cell/Tissue
NEET
1

a(i), b(ii), c(iii), d(iv)

2

a(iv), b(iii), c(ii), d(i)

3

a(ii), b(iv), c(iii), d(i)

4

a(iv), b(i), c(ii), d(iii)

Solution:

Let's match the items from Column-A with Column-B:

a. Catalase: Catalase is an enzyme that contains a Haem (or Heme) group as a prosthetic group, which is essential for its catalytic activity. So, a matches with (iv) Haem.

b. Nuclease: Nuclease is an enzyme that breaks down nucleic acids (DNA or RNA) by hydrolyzing the phosphodiester bonds. Enzymes that catalyze hydrolysis reactions are classified as hydrolases. So, b matches with (iii) Hydrolase.

c. Purine: Purines (like Adenine and Guanine) are nitrogenous bases that are components of nucleic acids. They are characterized by their double-ring, heterocyclic structure. So, c matches with (ii) Heterocyclic ring structure.

d. Starch: Starch is a complex carbohydrate (polysaccharide) that serves as the primary long-term energy storage molecule in plants. So, d matches with (i) Storehouse of energy in plants.

Combining these matches:

a - (iv)

b - (iii)

c - (ii)

d - (i)

This corresponds to option (2).
