Which one is found in ATP ribonucleotide

Options

A. Guanine
B. Uracil
C. Adenine
D. None of these

Answer

To determine which component is found in ATP (adenosine triphosphate), we need to analyze the structure of ATP and its components step by step.

### Step-by-Step Solution:

1. **Understanding ATP Structure**:
- ATP is a nucleotide that consists of three main components: a nitrogenous base, a sugar, and phosphate groups.

2. **Identifying the Nitrogenous Base**:
- The nitrogenous base in ATP is adenine. This is a purine base, which is one of the two categories of nitrogenous bases (the other being pyrimidines).

3. **Identifying the Sugar**:
- The sugar in ATP is ribose, which is a five-carbon sugar. This sugar is part of the ribonucleotide structure.

4. **Identifying the Phosphate Groups**:
- ATP contains three phosphate groups (triphosphate). These phosphate groups are responsible for the energy-carrying capacity of ATP.

5. **Conclusion**:
- Therefore, the component found in ATP ribonucleotide is adenine, which is the nitrogenous base.

### Final Answer:
Adenine is found in ATP ribonucleotide.
