Which of the following is known as the universal energy currency of the cell?

Options

A. ATP
B. AMP
C. DNA
D. RNA

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the molecule that is referred to as the "universal energy currency" of the cell.

2. **Identifying the Options**: The options provided are:
- A) ATP (Adenosine Triphosphate)
- B) AMP (Adenosine Monophosphate)
- C) DNA (Deoxyribonucleic Acid)
- D) RNA (Ribonucleic Acid)

3. **Analyzing ATP**:
- ATP stands for Adenosine Triphosphate. It consists of a nitrogenous base (adenine), a sugar (ribose), and three phosphate groups.
- The bonds between these phosphate groups are known as phosphate anhydride bonds, which are high-energy bonds.

4. **Energy Release from ATP**:
- When ATP is hydrolyzed (broken down), it releases energy. This process converts ATP into ADP (Adenosine Diphosphate) and an inorganic phosphate (Pi). The energy released during this reaction is significant and is used by the cell to perform various functions.

5. **Comparing with Other Options**:
- **AMP** (Adenosine Monophosphate) has only one phosphate group and does not serve as a major energy carrier in the cell.
- **DNA** and **RNA** are nucleic acids that carry genetic information but do not function as energy carriers.

6. **Conclusion**: Based on the analysis, ATP is recognized as the universal energy currency of the cell due to its ability to store and release energy efficiently.

**Final Answer**: The universal energy currency of the cell is **ATP (Adenosine Triphosphate)**.
