Question

Match the following

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

Hint:

Remember that collagen is a structural protein found in connective tissue, and guanine is a nitrogenous base found in nucleic acids.

Answer 1

The Correct Option is A

Matching List A with List B

Let's match the items from List A with List B:

• I. Aromatic amino acid: Aromatic amino acids such as phenylalanine, tyrosine, and tryptophan are involved in the formation of proteins and metabolic pathways. Match: D - Tryptophan.
• II. Phospholipid: Phospholipids are major components of biological membranes. They contain a glycerol backbone, two fatty acid chains, and a phosphate group. Match: A - Lecithin (a type of phospholipid).
• III. Heterocyclic compounds: Guanine is an example of a heterocyclic compound, as it contains a nitrogenous ring structure and is a part of nucleic acids. Match: B - Guanine.
• IV. Intracellular ground substance: The intracellular matrix often contains collagen, which is a structural protein found in connective tissue. Match: C - Collagen.

Thus, the correct matching is:

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

The correct answer is (1) I-D, II-A, III-B, IV-C.
