Question

Match the hormones in Group I with their functions in Group II. 
         Group I                                        Group II 
P) Aldosterone                                1) Stimulates the synthesis and secretion of androgens from the testes 
Q) Luteinizing hormone (LH)          2) Helps in the re-absorption of Na\(^+\) and water from the kidney 
R) Atrial natriuretic factor (ANF)     3) Increases the heart rate and the strength of heart contraction 
S) Epinephrine                                4) Causes dilation of blood vessels and reduction of blood pressure 
 

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

Hint:

Hormones have specific functions, and matching them with their correct physiological roles is crucial for understanding their effects in the body.

Answer 1

The Correct Option is B

Step 1: Understanding the hormones. 
- Aldosterone (P) helps in the reabsorption of Na\(^+\) and water from the kidney, which leads to water retention and increased blood pressure. 

- Luteinizing hormone (LH) (Q) stimulates the synthesis and secretion of androgens from the testes. 

- Atrial natriuretic factor (ANF) (R) causes dilation of blood vessels and reduces blood pressure. 

- Epinephrine (S) increases the heart rate and the strength of heart contraction, and is commonly known as adrenaline. 
 

Step 2: Analyzing the options. 
(A) P-2, Q-3, R-4, S-1: Incorrect — This does not match the correct functions for each hormone. 
(B) P-2, Q-1, R-4, S-3: Correct — This correctly matches each hormone with its function: - Aldosterone (P) helps in reabsorption (P-2), - Luteinizing hormone (Q) stimulates androgen synthesis (Q-1), - ANF (R) causes dilation and reduces blood pressure (R-4), - Epinephrine (S) increases heart rate and contraction (S-3). 
(C) P-1, Q-2, R-3, S-4: Incorrect — This does not match the correct functions for each hormone. 
(D) P-3, Q-4, R-2, S-1: Incorrect — This does not match the correct functions for each hormone. 
 

Step 3: Conclusion. 
The correct answer is (B) P-2, Q-1, R-4, S-3, as this matches each hormone with its correct function.
