Formation of glucose from proteins/surplus amino acids is

Options

A. Gylcogenolysis
B. Glycogenesis
C. Gluconeogenesis
D. Glycolysis

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the process of forming glucose from proteins or surplus amino acids.

2. **Identifying Relevant Processes**: There are several metabolic processes related to glucose metabolism:
- Glycogenesis: The formation of glycogen from glucose.
- Glycogenolysis: The breakdown of glycogen into glucose.
- Glycolysis: The breakdown of glucose to produce energy.
- Gluconeogenesis: The formation of glucose from non-carbohydrate sources.

3. **Analyzing Each Process**:
- **Glycogenesis**: This process is not relevant to the question as it involves converting glucose into glycogen for storage.
- **Glycogenolysis**: This process is also not relevant as it refers to breaking down glycogen into glucose, not forming glucose.
- **Glycolysis**: This process involves the breakdown of glucose, which is not what the question is asking.
- **Gluconeogenesis**: This is the key process that involves the formation of glucose from non-carbohydrate sources, including proteins and surplus amino acids.

4. **Conclusion**: The correct answer to the question is "Gluconeogenesis," as it specifically refers to the synthesis of glucose from non-carbohydrate sources like proteins.

**Final Answer**: The formation of glucose from proteins or surplus amino acids is termed as **Gluconeogenesis**.
