During glycolysis, fructose 1, 6-biphosphate is split into

Options

A. Dihydroxyacetone phosphate and 2-phosphoglyceraldehyde
B. Dihydroxy acetone phosphate and 1-phosphoglyceraldehyde
C. Dihydroxyacetone phosphate and 2-phosphoglyceraldehyde
D. Dihydroxyacetone phosphate and 3-phosphoglyceraldehyde.

Answer

**Step-by-Step Solution:**

1. **Understanding Glycolysis**: Glycolysis is a metabolic pathway that breaks down glucose (C6H12O6) into pyruvate. It consists of a series of enzyme-catalyzed reactions that occur in the cytoplasm of the cell.

2. **Identifying Fructose 1,6-bisphosphate**: In glycolysis, fructose 1,6-bisphosphate is an important intermediate formed from fructose 6-phosphate through phosphorylation.

3. **Splitting of Fructose 1,6-bisphosphate**: During the second stage of glycolysis, specifically in the fourth step, fructose 1,6-bisphosphate is split into two three-carbon molecules. This reaction is catalyzed by the enzyme aldolase.

4. **Products of the Splitting Reaction**: The splitting of fructose 1,6-bisphosphate results in the formation of two specific molecules:
- Dihydroxyacetone phosphate (DHAP)
- 3-phosphoglyceraldehyde (3-PGA)

5. **Conclusion**: Therefore, during glycolysis, fructose 1,6-bisphosphate is split into dihydroxyacetone phosphate and 3-phosphoglyceraldehyde.

**Final Answer**: Dihydroxyacetone phosphate and 3-phosphoglyceraldehyde.
