WebMar 6, 2006 · Phosphodiester linkages, including those that join the nucleotides of DNA, are highly resistant to spontaneous hydrolysis. The rate of water attack at the phosphorus atom of phosphodiesters is known only as an upper limit, based on the hydrolysis of the dimethyl phosphate anion. WebWhat happens during ATP hydrolysis quizlet? Bonds are broken by hydrolysis. When the terminal phosphate bond is broken by the addition of a water molecule, a molecule of inorganic phosphate leaves the ATP, which becomes adenosine diphosphate (ADP). This reaction is exergonic and releases energy.
