Which of the following enzyme is responsible for formation of glucose from glucose-6-phosphate?

Options

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

Answer

To determine which enzyme is responsible for the formation of glucose from glucose-6-phosphate, we can analyze the options provided: Kinase, Aldolase, Dehydrogenase, and Phosphatase.

### Step-by-Step Solution:

1. **Understanding the Reaction**: The conversion of glucose-6-phosphate to glucose involves the removal of a phosphate group from glucose-6-phosphate.

2. **Analyzing the Enzymes**:
- **Kinase**: This type of enzyme typically adds a phosphate group to a substrate. In the case of glucose, a kinase would convert glucose to glucose-6-phosphate, not the other way around. Therefore, it is not the correct answer.

- **Aldolase**: This enzyme catalyzes the cleavage of fructose-1,6-bisphosphate into two three-carbon molecules. It does not play a role in the conversion of glucose-6-phosphate to glucose. Thus, this option is also incorrect.

- **Dehydrogenase**: This enzyme is involved in oxidation-reduction reactions, specifically in the removal of hydrogen atoms from a molecule. It does not facilitate the removal of phosphate groups. Hence, this option is not correct either.

- **Phosphatase**: This enzyme catalyzes the removal of a phosphate group from a molecule, which is exactly what happens when glucose-6-phosphate is converted to glucose. Therefore, phosphatase is the enzyme responsible for this reaction.

3. **Conclusion**: The correct enzyme responsible for the formation of glucose from glucose-6-phosphate is **Phosphatase**.

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