Fructose 1, 6-Bisphosphate splits into DHAP and GAP. These two are

Options

A. Four carbon sugars
B. Three carbon sugars
C. Five carbon sugars
D. hexoses

Answer

### Step-by-Step Solution:

1. **Understanding the Reaction**: The question states that fructose 1,6-bisphosphate splits into DHAP (dihydroacetone phosphate) and GAP (glyceraldehyde 3-phosphate).

2. **Identifying the Compounds**:
- Fructose 1,6-bisphosphate is a 6-carbon sugar (hexose).
- Upon splitting, it produces two molecules: DHAP and GAP.

3. **Determining the Number of Carbons in DHAP and GAP**:
- DHAP (dihydroacetone phosphate) has 3 carbon atoms.
- GAP (glyceraldehyde 3-phosphate) also has 3 carbon atoms.

4. **Conclusion**: Since both DHAP and GAP are 3-carbon sugars, the correct answer to the question is that these two are 3-carbon sugars.

### Final Answer:
The two compounds, DHAP and GAP, are 3-carbon sugars.
