"WebAs a result of ATP hydrolysis, ADP (adenosine diphosphate) and Pi (inorganic phosphate) are produced. Step 2: ATP couples exergonic and endergonic reactions The exergonic reaction releases energy, whereas the endergonic reaction absorbs energy. Thus, exergonic reactions are coupled to endergonic reactions. " - How does atp couple chemical reactions
