Gluconeogenesis is controlled by

Options

A. Corticosterone
B. Thyroxine
C. Cortisol
D. All the above.

Answer

**Step-by-Step Solution:**

1. **Understanding Gluconeogenesis**: Gluconeogenesis is the metabolic process through which glucose is synthesized from non-carbohydrate precursors. This is particularly important during fasting or intense exercise when glucose levels need to be maintained.

2. **Identifying Hormonal Control**: Several hormones play a role in regulating gluconeogenesis. The question asks which hormones are involved in this process.

3. **Analyzing the Options**:
- **A. Corticosterone**: This hormone is a glucocorticoid produced by the adrenal cortex and is known to stimulate gluconeogenesis.
- **B. Thyroxine**: This thyroid hormone also influences carbohydrate metabolism and can enhance gluconeogenesis.
- **C. Cortisol**: Another glucocorticoid, cortisol, is well-known for its role in promoting gluconeogenesis, especially during stress.
- **D. All of the above**: This option suggests that all the listed hormones are involved in the control of gluconeogenesis.

4. **Conclusion**: Since corticosterone, thyroxine, and cortisol all contribute to the stimulation of gluconeogenesis, the correct answer is option D: All of the above.

**Final Answer**: D. All of the above.
