If 'X' is a hormone which controls the carbohydrate metabolism in the body and 'Y' is a hormone which controls the secretion of 'X', then 'X' arid 'Y' are

Options

A. insulin and somatotrophin
B. Aldosterone and growth hormone
C. Glucocorticoid and ACTH respectively
D. Glucocorticoid and GHRH

Answer

To solve the question regarding the hormones 'X' and 'Y', we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Role of Hormone 'X':**
- The question states that 'X' is a hormone that controls carbohydrate metabolism in the body.
- The primary hormones involved in carbohydrate metabolism are insulin, glucagon, and glucocorticoids.

2. **Determine the Function of Hormone 'Y':**
- Hormone 'Y' is described as a hormone that controls the secretion of 'X'.
- This implies that 'Y' is likely a regulatory hormone that stimulates or inhibits the release of 'X'.

3. **Analyze the Options Provided:**
- The options given are:
1. Insulin and somatotrophin
2. Aldosterone and growth hormone
3. Glucocorticoid and ACTH
4. Glucocorticoid and GHRH

4. **Evaluate Each Option:**
- **Option 1:** Insulin and somatotrophin - Insulin regulates glucose levels but is not controlled by somatotrophin.
- **Option 2:** Aldosterone and growth hormone - Aldosterone regulates sodium and potassium, not carbohydrate metabolism.
- **Option 3:** Glucocorticoid and ACTH - Glucocorticoids (like cortisol) are involved in carbohydrate metabolism, and their secretion is stimulated by ACTH (adrenocorticotropic hormone).
- **Option 4:** Glucocorticoid and GHRH - GHRH (growth hormone-releasing hormone) does not regulate glucocorticoids.

5. **Conclusion:**
- Based on the evaluation, the correct answer is **Option 3: Glucocorticoid and ACTH**. Here, 'X' is glucocorticoid, which controls carbohydrate metabolism, and 'Y' is ACTH, which controls the secretion of glucocorticoids.

### Final Answer:
- **X is glucocorticoid and Y is ACTH.**
