Phosphorylation of glucose with the help of ATP and hexokinase produces

Options

A. Glucose 1-phosphate
B. Glucose 6-phosphate
C. Glucose 1,6-biphosphate
D. Fructose, 1,6-biphosphate

Answer

To solve the question regarding the phosphorylation of glucose with the help of ATP and hexokinase, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Phosphorylation**: Phosphorylation is the process of adding a phosphate group to a molecule. In this case, we are adding a phosphate group to glucose.

2. **Identifying the Reactants**: The reactants involved in this process are glucose, ATP (adenosine triphosphate), and the enzyme hexokinase.

3. **Role of Hexokinase**: Hexokinase is the enzyme that catalyzes the phosphorylation of glucose. It facilitates the transfer of a phosphate group from ATP to glucose.

4. **ATP Conversion**: During the phosphorylation process, ATP is converted into ADP (adenosine diphosphate). This reaction releases one phosphate group that is then attached to glucose.

5. **Formation of Glucose 6-Phosphate**: The product of this reaction is glucose 6-phosphate. This is the result of the addition of the phosphate group to the sixth carbon of the glucose molecule.

6. **Eliminating Incorrect Options**:
- Glucose 1-phosphate is not produced in this reaction; it is formed in the pentose phosphate pathway.
- Fructose 1,6-bisphosphate is formed later in glycolysis, not during the phosphorylation of glucose.
- Glucose 1,6-bisphosphate is also not the product of this reaction.

7. **Conclusion**: Therefore, the correct answer to the question is that the phosphorylation of glucose with the help of ATP and hexokinase produces glucose 6-phosphate.

### Final Answer:
The phosphorylation of glucose with the help of ATP and hexokinase produces **glucose 6-phosphate**.
