D. 12

Answer

To determine the net number of water molecules produced per molecule of glucose during aerobic respiration, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Aerobic Respiration**:
- Aerobic respiration is a biochemical process in which glucose (C6H12O6) is broken down in the presence of oxygen (O2) to produce carbon dioxide (CO2), water (H2O), and energy (ATP).

2. **Chemical Equation**:
- The overall balanced equation for aerobic respiration of glucose is:
\[ C_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O + 36ATP \]
- This equation shows that one molecule of glucose reacts with six molecules of oxygen to produce six molecules of carbon dioxide, six molecules of water, and 36 molecules of ATP.

3. **Identifying Water Production**:
- From the balanced equation, we see that for every molecule of glucose that is completely oxidized during aerobic respiration, six molecules of water are produced.

4. **Conclusion**:
- Therefore, the net number of water molecules produced per molecule of glucose during aerobic respiration is **6**.

### Final Answer:
The net number of water molecules produced per molecule of glucose during aerobic respiration is **6**.
