Much of the suitability of ATP as an energy intermediary is related to the instability of the bonds between the phosphate groups. These bonds are unstable because . View Available Hint(s)for Part A they are hydrogen bonds, which are only about 10% as strong as covalent bonds the bonds between the phosphate groups are unusually strong and breaking them releases free energy the valence electrons in the phosphorus atom have less energy on average than those of other atoms the phosphate groups are polar and are attracted to the water in the cell's interior the negatively charged phosphate groups vigorously repel one another and the terminal phosphate group is more stable in water than it is in ATP
