What is formed by the breakdown of fructose 1, 6 bisphosphate in glycolysis?

Options

A. PGAL
B. DHAP
C. Both (a) and (b)
D. PGA

Answer

### Step-by-Step Solution:

1. **Identify the Compound**: The question asks about the breakdown of fructose-1,6-bisphosphate during glycolysis.

2. **Understand the Breakdown Process**: In glycolysis, fructose-1,6-bisphosphate is split into two different molecules.

3. **Identify the Products**: The two products formed from the breakdown of fructose-1,6-bisphosphate are:
- **Phosphoglyceraldehyde (PGAL)**: This is one of the products formed.
- **Dihydroxyacetone phosphate (DHAP)**: This is the second product formed.

4. **Enzyme Involved**: The enzyme that catalyzes the breakdown of fructose-1,6-bisphosphate into these two products is called **aldolase**.

5. **Final Conclusion**: Therefore, the breakdown of fructose-1,6-bisphosphate in glycolysis results in the formation of both phosphoglyceraldehyde (PGAL) and dihydroxyacetone phosphate (DHAP).

6. **Correct Answer**: The correct answer to the question is that both PGAL and DHAP are formed.
