B. 3-phosphoglycerate
C. 2-phosphoglycerate
D. Phosphophenol pyruvate.

Answer

To solve the question "3-Phosphoglyceraldehyde is oxidised in glycolysis to form," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Glycolysis**: Glycolysis is a metabolic pathway that breaks down glucose to produce energy. It consists of two main phases: the preparatory phase and the payoff phase.

2. **Identifying the Compound**: The question refers to 3-Phosphoglyceraldehyde, which is also known as Glyceraldehyde 3-phosphate (G3P). This compound is involved in the glycolysis pathway.

3. **Location in Glycolysis**: The oxidation of 3-Phosphoglyceraldehyde occurs during the payoff phase of glycolysis. This is where ATP and NADH are produced.

4. **Oxidation Reaction**: In the glycolytic pathway, 3-Phosphoglyceraldehyde is oxidized to form 1,3-Bisphosphoglycerate. This reaction is catalyzed by the enzyme glyceraldehyde 3-phosphate dehydrogenase.

5. **Energy Generation**: During this oxidation, NAD+ is reduced to NADH, which is a crucial step for energy production in the cell.

6. **Conclusion**: Therefore, the product formed from the oxidation of 3-Phosphoglyceraldehyde in glycolysis is **1,3-Bisphosphoglycerate**.

### Final Answer:
3-Phosphoglyceraldehyde is oxidised in glycolysis to form **1,3-Bisphosphoglycerate**.
