Synthesis of glucose from sources other than carbohydrate is called

Options

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

Answer

To solve the question "Synthesis of glucose from sources other than carbohydrate is called," follow these steps:

### Step 1: Understand the Process of Glucose Synthesis
- Glucose can be synthesized in the body through various metabolic pathways. One key pathway is the conversion of non-carbohydrate sources into glucose.

### Step 2: Identify Non-Carbohydrate Sources
- Non-carbohydrate sources that can be converted into glucose include proteins and fats. This process allows the body to maintain glucose levels even when carbohydrate intake is low.

### Step 3: Define the Term
- The specific term used for the synthesis of glucose from non-carbohydrate sources is "gluconeogenesis." This term combines "gluco-" referring to glucose and "neo-" meaning new, indicating the formation of new glucose molecules.

### Step 4: Eliminate Incorrect Options
- Review the other metabolic processes mentioned:
- **Glycolysis**: This is the breakdown of glucose into pyruvate, not the synthesis of glucose.
- **Glycogenolysis**: This refers to the breakdown of glycogen into glucose, which is also not relevant to the synthesis from non-carbohydrate sources.

### Step 5: Conclude with the Correct Answer
- Based on the definitions and processes discussed, the correct answer to the question is "gluconeogenesis."

### Final Answer:
The synthesis of glucose from sources other than carbohydrate is called **gluconeogenesis**.
