Organic compound found in most cells is

Options

A. Water
B. Glucose
C. Oxygen
D. Sodium chloride.

Answer

To determine the organic compound found in most cells, we can analyze the given options: water, glucose, oxygen, and sodium chloride.

### Step-by-Step Solution:

1. **Understanding the Options**:
- **Water**: While essential for life, it is not an organic compound.
- **Glucose**: A simple sugar and a monosaccharide, composed of carbon, hydrogen, and oxygen. It is a primary energy source for cells.
- **Oxygen**: A vital element for aerobic respiration but not an organic compound.
- **Sodium Chloride**: An inorganic compound, commonly known as table salt.

2. **Identifying Organic Compounds**:
- Organic compounds are primarily composed of carbon atoms. Among the options, glucose fits this definition as it contains carbon, hydrogen, and oxygen.

3. **Role of Glucose in Cells**:
- Glucose is crucial for cellular respiration. It is transported in the blood and utilized by cells to produce energy through processes like glycolysis, the TCA cycle, and the electron transport chain.

4. **Conclusion**:
- Given that glucose is a fundamental organic compound found in most cells and serves as a primary energy source, the correct answer is **glucose**.

### Final Answer:
The organic compound found in most cells is **glucose**.
