In the organism, energy is stored in the form of

Options

A. ATP
B. ADP
C. AMP
D. All the above.

Answer

To answer the question "In the organism, energy is stored in the form of," we will analyze the options provided: ATP, ADP, AMP, and all of the above.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **ATP (Adenosine Triphosphate)**: This molecule consists of an adenosine molecule bonded to three phosphate groups. It is known as the primary energy carrier in cells.
- **ADP (Adenosine Diphosphate)**: This molecule consists of an adenosine molecule bonded to two phosphate groups. It is formed when ATP loses one phosphate group and releases energy.
- **AMP (Adenosine Monophosphate)**: This molecule consists of an adenosine molecule bonded to one phosphate group. It is formed when ADP loses another phosphate group.

2. **Energy Storage in ATP**:
- ATP is known as the "energy currency" of the cell because it contains high-energy phosphate bonds. When these bonds are hydrolyzed (broken), a significant amount of energy is released, which can be used for various cellular processes.

3. **Comparison of Energy Storage**:
- **ATP** has two high-energy phosphate bonds, making it the most efficient form for energy storage.
- **ADP** has one high-energy bond, which means it stores less energy than ATP.
- **AMP** has no high-energy bonds, making it the least effective for energy storage.

4. **Conclusion**:
- Since ATP is the primary molecule used for energy storage in organisms due to its high-energy bonds, the correct answer to the question is **ATP**.

### Final Answer:
In the organism, energy is stored in the form of **ATP (Adenosine Triphosphate)**.
