Pick out the incorrect statement about ATP.

Options

A. It is a nucleotide
B. It contains the purine, adenine
C. The enzyme - catalysed hydrolysis ATP is ADP and AMP is accompanied by absorption of energy
D. Energy is stored in the cell in form of ATP

Answer

To solve the question of identifying the incorrect statement about ATP, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding ATP**:
- ATP stands for Adenosine Triphosphate. It is known as the energy currency of the cell because it stores and provides energy for various cellular processes.

2. **Analyzing Option A**:
- **Statement**: "It is a nucleotide."
- **Evaluation**: ATP is indeed a nucleotide, consisting of a nitrogenous base (adenine), a pentose sugar (ribose), and three phosphate groups.
- **Conclusion**: This statement is correct.

3. **Analyzing Option B**:
- **Statement**: "It contains purine adenine."
- **Evaluation**: The nitrogenous base in ATP is adenine, which is classified as a purine.
- **Conclusion**: This statement is correct.

4. **Analyzing Option C**:
- **Statement**: "The enzyme catalyzed hydrolysis of ATP to ADP and AMP is accompanied by absorption of energy."
- **Evaluation**: When ATP is hydrolyzed into ADP and AMP, energy is released, not absorbed. This process is exergonic, meaning it releases energy that the cell can use for various functions.
- **Conclusion**: This statement is incorrect.

5. **Analyzing Option D**:
- **Statement**: "Energy is stored in the cell in the form of ATP."
- **Evaluation**: ATP is indeed the primary molecule for storing and transferring energy in cells.
- **Conclusion**: This statement is correct.

### Final Answer:
The incorrect statement about ATP is **Option C**.
