Which one is responsible for produce energy in bio reaction:

Options

A. Thyroxine
B. Adrenelene
C. Oestrogen
D. Projestrone

Answer

To determine which hormone is responsible for the production of energy in bioreactions, we can analyze the given options: thyroxine, adrenaline, estrogen, and progesterone.

### Step-by-Step Solution:

1. **Identify the hormones and their sources**:
- **Thyroxine**: Secreted by the thyroid gland.
- **Adrenaline**: Produced by the adrenal glands.
- **Estrogen**: Secreted by the ovaries.
- **Progesterone**: Also secreted by the ovaries.

2. **Understand the functions of each hormone**:
- **Thyroxine**: It plays a crucial role in regulating metabolism. It controls various biochemical reactions that involve the burning of proteins, carbohydrates, and fats to release energy.
- **Adrenaline**: Primarily involved in the fight-or-flight response, it increases heart rate and blood pressure but does not directly produce energy.
- **Estrogen**: Responsible for the development of female sex organs and secondary sexual characteristics, not directly involved in energy production.
- **Progesterone**: Maintains pregnancy and prepares the body for potential pregnancy; it does not have a direct role in energy production.

3. **Determine the hormone responsible for energy production**:
- Among the hormones listed, **thyroxine** is the only one that directly influences metabolic processes that produce energy by facilitating the burning of fats, proteins, and carbohydrates.

4. **Conclusion**:
- Therefore, the correct answer is **thyroxine**, as it is responsible for the production of energy in bioreactions.

### Final Answer:
The hormone responsible for the production of energy in bioreactions is **thyroxine**.
