During photosynthesis , the oxygen from `CO_2` is incorporated into

Options

A. Oxygen gas
B. Water
C. Carbohydrates
D. `NADPH_2`

Answer

To solve the question "During photosynthesis, the oxygen from CO₂ is incorporated into," we can follow these steps:

### Step 1: Understand the Process of Photosynthesis
Photosynthesis is the process by which green plants convert light energy into chemical energy, using carbon dioxide (CO₂) and water (H₂O) to produce glucose and oxygen (O₂).

### Step 2: Identify the Key Components
- **Light Energy**: Essential for the process, absorbed by chlorophyll.
- **Water (H₂O)**: Undergoes photolysis during the light reactions, releasing oxygen.
- **Carbon Dioxide (CO₂)**: Used in the dark reactions (Calvin cycle) for carbon fixation.

### Step 3: Focus on the Role of CO₂
During photosynthesis, CO₂ is fixed into organic molecules through a series of reactions in the Calvin cycle. The oxygen atoms from CO₂ are incorporated into glucose (C₆H₁₂O₆) during this process.

### Step 4: Identify the Products
The main product of the photosynthesis process is glucose, which is a carbohydrate. The oxygen released during photosynthesis primarily comes from the photolysis of water, not directly from CO₂.

### Step 5: Conclusion
The oxygen from CO₂ is incorporated into glucose during the process of photosynthesis.

### Final Answer
The oxygen from CO₂ is incorporated into glucose.
