Fructose 1,6 bisphosphate `rarr` Fructose 6 phosphate + Pi The enzyme that catalyses the above reaction belongs to this class

Options

A. Transferases
B. Oxidoreductases
C. Ligases
D. Hydrolases

Answer

To determine the class of the enzyme that catalyzes the reaction of converting fructose 1,6-bisphosphate to fructose 6-phosphate plus inorganic phosphate (Pi), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reaction**: The reaction given is:
\[ \text{Fructose 1,6-bisphosphate} \rightarrow \text{Fructose 6-phosphate} + \text{Pi} \]
Here, fructose 1,6-bisphosphate is being converted into fructose 6-phosphate, and a phosphate group (Pi) is released.

2. **Analyze the Changes**: In this reaction, we notice that one phosphate group is removed from fructose 1,6-bisphosphate, converting it into fructose 6-phosphate. This indicates that a phosphate group is being transferred or removed.

3. **Classify the Enzyme**: The enzyme that catalyzes this type of reaction is involved in transferring phosphate groups. The options provided are:
- Transferase
- Oxidoreductase
- Ligases
- Hydrolysis

Since the reaction involves the transfer of a phosphate group, the appropriate class of enzyme is **Transferase**. Transferases are enzymes that facilitate the transfer of functional groups, such as phosphate groups, from one molecule to another.

4. **Eliminate Other Options**:
- **Oxidoreductase**: These enzymes are involved in oxidation-reduction reactions, which is not applicable here since we are not oxidizing or reducing any molecules.
- **Ligases**: These enzymes are responsible for joining two molecules together, which is not the case in this reaction.
- **Hydrolysis**: This involves the addition of water to break down molecules, which is also not relevant to the reaction described.

5. **Conclusion**: Therefore, the enzyme that catalyzes the conversion of fructose 1,6-bisphosphate to fructose 6-phosphate plus Pi belongs to the class of **Transferases**.

### Final Answer:
The enzyme that catalyzes the reaction is a **Transferase**.
