Which of the following is a hormone responsible for the regulation of blood glucose level ?

Options

A. Tetraiodothyroine and triiodothyronine
B. Trihydroxyidothyronine and thymosin
C. Aldosterone and calcitonin
D. Androgen and FSH

Answer

To determine which hormone is responsible for the regulation of blood glucose levels, we can analyze the options provided in the question.

### Step-by-Step Solution:

1. **Identify the Hormones in Each Option**:
- **Option 1**: Tetraiodothyronine (T4) and T3 (Triiodothyronine)
- **Option 2**: Dihydroxy iodothyronine and Thymosine
- **Option 3**: Aldosterone and Calcitonin
- **Option 4**: Endocannabinoic acid

2. **Analyze Each Option**:
- **Option 1**: T4 and T3 are hormones produced by the thyroid gland. They primarily regulate metabolism, including the metabolism of carbohydrates, proteins, and fats. However, they are not the main hormones responsible for blood glucose regulation.
- **Option 2**: Dihydroxy iodothyronine and Thymosine are associated with the thymus gland and immune function, not blood glucose regulation.
- **Option 3**: Aldosterone is a hormone that helps regulate sodium and potassium levels in the body, while Calcitonin is involved in calcium homeostasis. Neither of these hormones directly regulates blood glucose levels.
- **Option 4**: Endocannabinoic acid is involved in various physiological processes but is not primarily known for regulating blood glucose levels.

3. **Identify the Correct Hormones**:
- The hormones that are primarily responsible for regulating blood glucose levels are **insulin** and **glucagon**. Insulin lowers blood glucose levels, while glucagon raises them. However, these hormones are not listed in the options provided.

4. **Conclusion**:
- Since none of the options directly mention insulin or glucagon, we conclude that the question might be misleading. However, based on the context of the video transcript, the correct answer should focus on the hormones that influence metabolism, which includes T3 and T4, even though they are not the primary regulators of blood glucose.

### Final Answer:
None of the options directly correspond to the primary hormones responsible for blood glucose regulation, which are insulin and glucagon. However, if we must select from the given options based on the context, **Option 1 (Tetraiodothyronine and T3)** is the most relevant, though not correct in the strictest sense.
