Nucleotide found in the cells is

Options

A. cAMP
B. AMP
C. ADP
D. ATP.

Answer

To solve the question "Nucleotide found in the cells is," we will analyze the provided options: Cyclic AMP, AMP, ADP, and ATP.

### Step-by-Step Solution:

1. **Understanding Nucleotides**:
- A nucleotide is a basic building block of nucleic acids. It consists of three components: a nitrogenous base, a sugar molecule (ribose or deoxyribose), and one or more phosphate groups.

2. **Analyzing the Options**:
- **Cyclic AMP (cAMP)**: This is a derivative of ATP and acts as a secondary messenger in cellular signaling. It is not typically found in large amounts in cells as it is produced and used quickly.
- **AMP (Adenosine Monophosphate)**: This nucleotide contains only one phosphate group. While it is a nucleotide, it is not the primary form found in cells for energy transfer.
- **ADP (Adenosine Diphosphate)**: This nucleotide has two phosphate groups. It is involved in energy transfer but is not the primary energy currency of the cell.
- **ATP (Adenosine Triphosphate)**: This nucleotide has three phosphate groups and is known as the energy currency of the cell. It is the most common nucleotide found in cells and is used for energy transfer in various metabolic processes.

3. **Conclusion**:
- Among the options provided, ATP is the nucleotide that is predominantly found in cells and serves as the main energy carrier. Therefore, the correct answer is **ATP**.

### Final Answer:
The nucleotide found in the cells is **ATP (Adenosine Triphosphate)**.
