Answer

To determine which of the following is an amine hormone, we can analyze the characteristics of various hormones mentioned in the transcript.

### Step-by-Step Solution:

1. **Understanding Hormone Types**:
- Hormones can be classified into different types based on their chemical structure: peptide hormones, steroid hormones, and amine hormones.
- Amine hormones are derived from amino acids and typically include hormones such as catecholamines (e.g., epinephrine, norepinephrine) and thyroid hormones (e.g., thyroxine).

2. **Identifying the Hormones**:
- **Insulin**: This is a peptide hormone secreted by the pancreas. It is not an amine hormone.
- **Steroid Hormones**: These are lipid-based hormones and include hormones like cortisol and testosterone. They are not classified as amine hormones.
- **Thyroxine (T4)**: This hormone is secreted by the thyroid gland and is derived from the amino acid tyrosine. It is classified as an amine hormone.

3. **Conclusion**:
- Among the hormones discussed, **thyroxine** is the only amine hormone.

### Final Answer:
The amine hormone among the options is **thyroxine**.
