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, we will analyze each statement provided in the question step by step.

### Step 1: Analyze the first statement
**Statement:** Hormones are non-nutrient chemicals.
**Analysis:** This statement is correct. Hormones are indeed non-nutrient chemicals produced by glands that help regulate various physiological processes in the body. They do not provide nutrients like carbohydrates, proteins, or fats.

### Step 2: Analyze the second statement
**Statement:** Hormones are considered as intercellular messengers.
**Analysis:** This statement is also correct. Hormones function as intercellular messengers, transmitting signals between different cells to coordinate functions and responses in the body.

### Step 3: Analyze the third statement
**Statement:** Hormones act only on their target cells through receptors.
**Analysis:** This statement is correct as well. Hormones exert their effects by binding to specific receptors on target cells. This interaction is crucial for the hormone's action.

### Step 4: Analyze the fourth statement
**Statement:** Fat-soluble hormones act through secondary messengers.
**Analysis:** This statement is incorrect. Fat-soluble hormones (such as steroid hormones) typically pass through the cell membrane and bind to intracellular receptors, directly influencing gene expression. They do not require secondary messengers to exert their effects.

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

### Final Answer
The incorrect statement about hormones is: **"Fat-soluble hormones act through secondary messengers."**
