Adrenaline and noradrenaline do not pomote

Options

A. Breakdown of proteins
B. Breakdown of lipids
C. Glycogenesis
D. Glycogenolysis

Answer

### Step-by-Step Solution:

1. **Understanding the Hormones**: Adrenaline and noradrenaline are hormones produced by the adrenal medulla. They are also referred to as catecholamines and are released during stressful situations, often termed the "fight or flight" response.

2. **Functions of Adrenaline and Noradrenaline**: These hormones have several physiological effects, primarily aimed at preparing the body for immediate physical activity. They are known for their catabolic roles, meaning they help break down various substances in the body to increase energy availability.

3. **Breakdown of Substances**:
- **Proteolysis**: Adrenaline and noradrenaline promote the breakdown of proteins into amino acids.
- **Lipolysis**: They also facilitate the breakdown of lipids (fats) into fatty acids and glycerol.
- **Glycogenolysis**: These hormones promote the breakdown of glycogen into glucose, which increases blood sugar levels.

4. **Glycogenesis**: This is the process of converting glucose into glycogen for storage. Adrenaline and noradrenaline do not promote this process. Instead, they inhibit glycogenesis to ensure that glucose is readily available for energy during stressful situations.

5. **Conclusion**: Based on the functions of adrenaline and noradrenaline, the correct answer to the question "Adrenaline and noradrenaline do not promote which of the following?" is **glycogenesis**.

### Final Answer:
**Glycogenesis (Option 3)**
