Question

Match the following:  

List-I (Hormone Type) 
A. Amine hormone 
B. Peptide hormone 
C. Protein hormone 
D. Steroid hormone 

List-II (Example) 
I. Oxytocin 
II. Oestrogen 
III. Trypsin 
IV. Insulin 
V. Epinephrine

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

Hint:

Epinephrine is an amine hormone, oxytocin is a peptide hormone, insulin is a protein hormone and oestrogen is a steroid hormone.

Answer 1

The Correct Option is D

Concept: Hormones are classified on the basis of their chemical nature into amine, peptide, protein and steroid hormones.

Step 1: Match Amine Hormone. Epinephrine (adrenaline) is derived from the amino acid tyrosine. Hence it is an amine hormone. \[ A \rightarrow V \]

Step 2: Match Peptide Hormone. Oxytocin is a peptide hormone composed of a short chain of amino acids. \[ B \rightarrow I \]

Step 3: Match Protein Hormone. Insulin is a protein hormone consisting of polypeptide chains. \[ C \rightarrow IV \]

Step 4: Match Steroid Hormone. Oestrogen is synthesized from cholesterol and belongs to steroid hormones. \[ D \rightarrow II \]

Step 5: Final matching. \[ A-V,\quad B-I,\quad C-IV,\quad D-II \] Hence option (D) is correct.
