When the terminal phosphate is cleaved from the adenosine triphosphate molecule, the products are adenosine diphosphate and inorganic phosphate, ATP + H20 > ADP + P, where P; stands for the various forms of phosphate that exist at the pH of the particular solution. If the total concentration of P, is 2.5 x 10-?M, what are the concentrations of the predominant forms of phosphate that exist at pH 7.4? H2N N: N- 0-P-0-P-O-P-O-
