Question

Match the following:

• A. A-II, B-III, C-IV, D-I
• B. A-IV, B-I, C-II, D-III
• C. A-IV, B-III, C-II, D-I
• D. A-IV, B-I, C-III, D-II % Based on image, option 4 has same initial parts as 2

Hint:

Key hormone functions: - Glucocorticoids (e.g., Cortisol): Regulate carbohydrate, protein, and fat metabolism; stress response; anti-inflammatory. - Mineralocorticoids (e.g., Aldosterone): Regulate salt (Na\(^+\), K\(^+\)) and water balance via kidneys. - Progesterone: "Pregnancy hormone"; prepares uterus for implantation, maintains pregnancy. - Estradiol (an Estrogen): Female secondary sexual characteristics, regulates menstrual cycle, ovulation.

Answer 1

The Correct Option is C

Let's match each hormone in List-I with its primary function from List-II.
A) Glucocorticoids (e.
g.
, cortisol): These are steroid hormones produced by the adrenal cortex.
They have widespread effects on metabolism.
- They stimulate gluconeogenesis (synthesis of glucose from non-carbohydrate sources).
- They increase blood glucose levels.
- They promote protein breakdown and fat mobilization.
- They have anti-inflammatory and immunosuppressive effects.
Function IV) "Control the carbohydrate metabolism" is a key function.
So, A matches with IV.
B) Mineralocorticoids (e.
g.
, aldosterone): These are steroid hormones produced by the adrenal cortex.
Their primary role is to regulate salt and water balance.
- Aldosterone acts on the kidneys to increase reabsorption of sodium (Na\(^+\)) and water, and increase excretion of potassium (K\(^+\)).
Function III) "Control the level of excretion of water and salt by the kidneys" is a key function.
So, B matches with III.
C) Progesterone: This is a steroid hormone primarily produced by the corpus luteum in the ovary after ovulation and by the placenta during pregnancy.
- It plays a crucial role in preparing the endometrium (uterine lining) for implantation of a fertilized egg.
- It maintains pregnancy.
- It inhibits uterine contractions during pregnancy.
Function II) "Prepares the uterus for implantation of fertilised egg" is a key function.
So, C matches with II.
D) Estradiol: This is the primary estrogen, a steroid hormone produced mainly by the ovaries in females.
- It is responsible for the development of female secondary sexual characteristics.
- It plays a key role in regulating the menstrual cycle (along with progesterone and other hormones like FSH and LH).
- It is involved in bone health, cardiovascular health, etc.
Function I) "In the control of menstrual cycle" is a key function.
So, D matches with I.
Matching sequence: A - IV B - III C - II D - I This corresponds to option (3).
