The intermediate of glycolysis which undergoes lysis or splitting is

Options

A. Dihydroxyacetone 3-phosphate
B. Fructose 1, 6-diphosphate
C. Glyceraldehyde 3-phosphate
D. Glucose 6-phosphate.

Answer

To solve the question regarding the intermediate of glycolysis that undergoes lysis or splitting, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Glycolysis**: Glycolysis is a metabolic pathway that converts glucose into pyruvate, producing ATP and NADH in the process. It consists of several steps, each involving different intermediates.

2. **Identify Key Intermediates**: In glycolysis, several intermediates are formed. The key intermediates include glucose-6-phosphate, fructose-6-phosphate, fructose-1,6-bisphosphate, dihydroxyacetone phosphate (DHAP), and glyceraldehyde-3-phosphate (G3P).

3. **Focus on the Splitting Step**: The question asks for the intermediate that undergoes lysis or splitting. This occurs during the conversion of fructose-1,6-bisphosphate (F1,6BP) into two three-carbon molecules: DHAP and G3P.

4. **Identify the Correct Intermediate**: The intermediate that undergoes lysis is fructose-1,6-bisphosphate. This compound is split into DHAP and G3P in the fourth step of glycolysis.

5. **Eliminate Incorrect Options**:
- **Glyceraldehyde-3-phosphate (G3P)**: This is produced later in glycolysis and does not undergo splitting.
- **Glucose-6-phosphate**: This is the first step of glycolysis and does not split.
- **Dihydroxyacetone phosphate (DHAP)**: This is one of the products of the splitting, not the intermediate that splits.

6. **Conclusion**: Therefore, the correct answer to the question is **fructose-1,6-bisphosphate**.

### Final Answer:
The intermediate of glycolysis which undergoes lysis or splitting is **fructose-1,6-bisphosphate**.
