Which of the following statement is incorrect for hormones?

Options

A. They are non-nutrient chemicals
B. Considered as intercellular messengers
C. Act only on their target cells through receptor
D. Fat soluble hormones act through secondary messengesr

Answer

To determine which statement about hormones is incorrect, let’s analyze the provided statements step by step:

1. **Hormones are non-nutrient chemicals considered as intercellular messengers.**
- This statement is correct. Hormones are indeed non-nutrient chemicals that facilitate communication between cells.

2. **Hormones act only on their target cell through receptors.**
- This statement is also correct. Hormones exert their effects by binding to specific receptors on their target cells.

3. **Fat-soluble hormones act through secondary messengers.**
- This statement is incorrect. Fat-soluble hormones, such as steroid hormones, typically pass through the cell membrane and bind to intracellular receptors, not through secondary messengers. Secondary messengers are usually involved with water-soluble hormones that bind to membrane receptors.

4. **Hormones are produced by endocrine glands.**
- This statement is correct. Hormones are indeed produced by endocrine glands, which are ductless glands that release hormones directly into the bloodstream.

5. **Endocrine glands are ductless glands.**
- This statement is correct. Endocrine glands do not have ducts; they release hormones directly into the bloodstream.

6. **Hormones are released in blood and transported to distantly located target organs.**
- This statement is correct. Hormones travel through the bloodstream to reach their target organs, which can be located far from their site of production.

Based on the analysis, the incorrect statement is: **"Fat-soluble hormones act through secondary messengers."**

### Step-by-Step Solution:
1. Identify the characteristics of hormones.
2. Review each statement provided.
3. Confirm the accuracy of each statement.
4. Identify the statement that does not align with the known functions of hormones.
5. Conclude that the incorrect statement is about fat-soluble hormones acting through secondary messengers.
