Question

Match the following from column 1 and column 2.
$\begin{array}{cc}\text{Column 1 (hormone)}& \text{Column 2 (chemical nature)}\\ \text{P. Estradiol}& \text{1.Protein hormone}\\ \text{Q. Thyroxine}& \text{2.Amino acid-derivative}\\ \text{R. Growth hormone}& \text{3.Steroid hormones}\\ \text{S. Epinephrine}& \text{4.Iodothyronines}\end{array}$

• A. P - 3, Q - 4, R - 1, S - 2
• B. P - 2, Q - 1, R - 4, S - 3
• C. P - 2, Q - 3, R - 4, S - 1
• D. P- 4, Q -1, R - 4. S - 3

Answer 1

The correct option is A P - 3, Q - 4, R - 1, S - 2

On the basis of their chemical nature, hormones can be divided into groups :
(i) Peptide, polypeptide, protein hormones
(ii) Steroids
(iii) Iodothyronines
(iv) Amino-acid derivatives

Estradiol is a steroid hormone. Thyroid hormones are iodothyronine. Thyroxine is a thyroid hormone so it is a iodothyronine. Pituitary hormones are protein hormones. Growth hormone is secreted by the anterior lobe of the pituitary. So it is a protein hormone. Epinephrine is an amino acid derivative hormone.
