Energy currency (reservior) of the cells is

Options

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

Answer

**Step-by-step Text Solution:**

1. **Understanding the Question**: The question asks for the "energy currency" of the cells. This term refers to the molecule that cells use to store and transfer energy for various biochemical processes.

2. **Identifying the Options**: The options provided are AMP, ATP, RNA, and DNA. We need to evaluate which of these is primarily responsible for energy transfer in cells.

3. **Analyzing Each Option**:
- **AMP (Adenosine Monophosphate)**: While AMP is involved in energy transfer, it is not the primary energy currency.
- **ATP (Adenosine Triphosphate)**: ATP is known as the main energy currency of the cell. It stores energy in its high-energy phosphate bonds.
- **RNA (Ribonucleic Acid)**: RNA is primarily involved in protein synthesis and does not serve as an energy currency.
- **DNA (Deoxyribonucleic Acid)**: DNA is the genetic material and is not involved in energy transfer.

4. **Conclusion**: Based on the analysis, ATP is the correct answer. It is synthesized from the breakdown of nutrients and releases energy when it is converted to ADP (Adenosine Diphosphate) and inorganic phosphate.

5. **Final Answer**: The energy currency (reservoir) of the cells is ATP.
