Options

A. `C_(6)H_(12)O_(6)+O_(2)`
B. `.^(14)C_(6)H_(12)O_(6)+O_(2)`
C. `.^(14)C_(6)H_(12)O_(6)+.^(18)O_(2)`
D. `C_(6)H_(12)O_(6)+O_(2)`.

Answer

To solve the question regarding the products formed when a photosynthesis cell is provided with `.^(14)CO_(2)` and `H_(2) .^(18)O`, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Inputs**:
- The cell is provided with two specific compounds:
- `.^(14)CO_(2)` which is carbon dioxide with a radioactive carbon isotope (C-14).
- `H_(2) .^(18)O` which is water with a radioactive oxygen isotope (O-18).

2. **Photosynthesis Overview**:
- Photosynthesis is the process by which plants convert carbon dioxide and water into glucose and oxygen using sunlight.
- The general equation for photosynthesis is:
\[ 6CO_2 + 6H_2O \rightarrow C_6H_{12}O_6 + 6O_2 \]

3. **Identifying the Source of Carbon and Oxygen**:
- In this scenario, the carbon in glucose will come from the carbon dioxide provided, specifically from the `.^(14)CO_(2)`.
- The oxygen released during photosynthesis comes from the water, which in this case is `H_(2) .^(18)O`.

4. **Determining the Products**:
- The glucose produced will have the carbon atoms labeled with C-14 from the `.^(14)CO_(2)`.
- The oxygen released as a byproduct will be labeled with O-18 from the `H_(2) .^(18)O`.

5. **Final Products**:
- Therefore, the products formed will be:
- Glucose (C-14 labeled): \( C_6H_{12}O_6 \)
- Oxygen (O-18 labeled): \( O_2 \)

### Conclusion:
The products formed when a photosynthesis cell is provided with `.^(14)CO_(2)` and `H_(2) .^(18)O` are glucose labeled with C-14 and oxygen labeled with O-18.
