Enzyme responsible for formation of glucose from glucose 6-phosphate is

Options

A. Dehydrogenase
B. Aldolase
C. Kinase
D. Phosphatase.

Answer

To determine the enzyme responsible for the formation of glucose from glucose 6-phosphate, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Reaction**: The question asks for the enzyme that converts glucose 6-phosphate into glucose. This is a dephosphorylation reaction where a phosphate group is removed from glucose 6-phosphate.

2. **Identifying the Enzyme**: The enzyme that catalyzes the removal of a phosphate group from glucose 6-phosphate is known as glucose 6-phosphatase. This enzyme specifically acts on glucose 6-phosphate to release inorganic phosphate and produce free glucose.

3. **Classifying the Enzyme**: Glucose 6-phosphatase belongs to the class of enzymes known as phosphatases. Phosphatases are enzymes that remove phosphate groups from molecules. Since this reaction involves the addition of water to facilitate the removal of the phosphate group, glucose 6-phosphatase is also classified under hydrolases, which are enzymes that catalyze the hydrolysis of chemical bonds.

4. **Conclusion**: Therefore, the enzyme responsible for the formation of glucose from glucose 6-phosphate is glucose 6-phosphatase.

### Final Answer:
The enzyme responsible for the formation of glucose from glucose 6-phosphate is **glucose 6-phosphatase**.
