The amount of water required to form one molecule of glucose in a photosynthetic reaction is

Options

A. 6 molecules
B. 10 molecules
C. 1 molecules
D. 12 molecules

Answer

To determine the amount of water required to form one molecule of glucose during photosynthesis, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Photosynthesis**: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, specifically glucose, using carbon dioxide and water.

2. **Photosynthesis Equation**: The overall balanced chemical equation for photosynthesis can be written as:
\[ 6CO_2 + 6H_2O \rightarrow C_6H_{12}O_6 + 6O_2 \]
This equation shows that six molecules of carbon dioxide and six molecules of water are used to produce one molecule of glucose and six molecules of oxygen.

3. **Identifying Water Requirement**: From the balanced equation, we can see that for every one molecule of glucose (C6H12O6) produced, six molecules of water (H2O) are required.

4. **Conclusion**: Therefore, the amount of water required to form one molecule of glucose in a photosynthetic reaction is **6 molecules of water**.

### Final Answer:
The amount of water required to form one molecule of glucose in a photosynthetic reaction is **6 molecules of water**.
