For undergoing glycolysis, glucose requires priming with the help of ATP

Options

A. 1
B. 2
C. 3
D. 4

Answer

### Step-by-Step Solution:

1. **Understanding Glycolysis**: Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing a small amount of energy in the form of ATP. It occurs in the cytoplasm of the cell.

2. **Raw Materials Required**: To initiate glycolysis, two primary raw materials are needed:
- A molecule of glucose.
- Molecules of ATP.

3. **ATP Requirement**: Glycolysis is a 10-step process, and to start this process, **two molecules of ATP** are required for the priming phase. This means that ATP is used to prepare glucose for breakdown.

4. **Energy Production**: Although glycolysis requires two ATP molecules to initiate, it ultimately produces four ATP molecules by the end of the process. However, the question specifically asks for the ATP needed to start glycolysis.

5. **Conclusion**: Therefore, the answer to the question is that **two molecules of ATP are required to initiate glycolysis**.

### Final Answer:
**Two molecules of ATP are required to initiate glycolysis.**
