The non-nutrient chemicals which acts as intercellular messengers and are produced in trace amounts are known as

Options

A. Enzymes
B. Mucous
C. Hormones
D. None

Answer

To solve the question, "The non-nutrient chemicals which act as intercellular messengers and are produced in trace amounts are known as," we can follow these steps:

### Step 1: Understand the Key Terms
- **Non-nutrient chemicals**: These are substances that do not provide nutritional value but have other important functions in the body.
- **Intercellular messengers**: These are chemicals that facilitate communication between cells.
- **Produced in trace amounts**: This indicates that these chemicals are present in very small quantities.

### Step 2: Analyze the Options
The options provided are:
1. Enzyme
2. Mucus
3. Hormone
4. None

### Step 3: Evaluate Each Option
- **Enzyme**: Enzymes are biological catalysts that speed up chemical reactions. They are not classified as intercellular messengers and are not produced in trace amounts.

- **Mucus**: Mucus is a thick fluid secreted by various organs to keep them moist and trap microbes. It does not serve as an intercellular messenger.

- **Hormone**: Hormones are indeed non-nutrient chemicals that act as intercellular messengers. They are produced in trace amounts and play crucial roles in regulating various physiological processes in the body.

- **None**: This option suggests that none of the other options are correct, which is not the case here.

### Step 4: Conclusion
Based on the analysis, the correct answer is **Hormone**. Hormones serve as intercellular messengers and are produced in small amounts, fulfilling the criteria set by the question.

### Final Answer
The non-nutrient chemicals which act as intercellular messengers and are produced in trace amounts are known as **hormones**.
