The high-energy bonds in a nucleotide are

High-energy bonds in a nucleotide refer to the bonds that connect the phosphate groups in molecules like ATP. These are the phosphate–phosphate links, called phosphoanhydride bonds, and they store a lot of energy. When one phosphate is released, energy is liberated to power many cellular processes. Hydrogen bonds are weak interactions used for base pairing, not energy storage, and ionic bonds aren’t the energy-storage bonds in nucleotides. While covalent bonds hold the atoms together, the energy-rich bonds relevant here are the bonds between phosphate groups. So, phosphate bonds best capture the concept of high-energy storage in nucleotides.
