In ATP high energy bond is present

Options

A. Nucleoside and phosphate group
B. Sugar and phosphate group
C. Base and phosphate group
D. None of the above.

Answer

**Step-by-Step Solution:**

1. **Understanding ATP Structure**: ATP (Adenosine Triphosphate) is a nucleotide composed of three main components: an adenine base (a purine), a ribose sugar, and three phosphate groups.

2. **Identifying High-Energy Bonds**: In ATP, the energy is stored in the bonds between the phosphate groups. There are two high-energy bonds present between the second and third phosphate groups.

3. **Analyzing the Bonds**:
- The first bond connects the ribose sugar to the first phosphate group. This bond is not considered a high-energy bond.
- The second bond connects the first phosphate group to the second phosphate group, and the third bond connects the second phosphate group to the third phosphate group. The second and third bonds are the high-energy bonds.

4. **Conclusion**: The high-energy bonds in ATP are specifically between the second phosphate group and the third phosphate group. Therefore, the correct answer to the question is that the high-energy bond is present between the phosphate groups.

5. **Final Answer**: None of the above (as the question does not specify the correct bond).
