pH-dependence of initial (admixture) adenosine triphosphate (ATP) changes (ATP synthesis and hydrolysis) was studied for aerated and deaerated aqueous solutions during the incubation of adenosine diphosphate (ADP) and inorganic phosphate (Pi) in the presence of reduced nicotinamide adenine dinucleotide (NADH) and riboflavin (Rf). The preferential pH regions were indicated both for ATP synthesis and ATP hydrolysis (pH less than pH 5.4, 5.9 divided by pH 6.5 and pH greater than 6.6, pH 5.5 divided by pH 5.8 respectively). 'Free radical content measurements were paralleled by ESR technique. On the basis of the obtained results it was assumed that a part of ESP signal attributed to ADP radicals was increased during ATP synthesis.
在还原型烟酰胺腺嘌呤二核苷酸（NADH）和核黄素（Rf）存在的情况下，对二磷酸腺苷（ADP）和无机磷酸盐（Pi）进行孵育时，研究了通气和脱气水溶液中初始（混合）三磷酸腺苷（ATP）变化（ATP合成和水解）的pH依赖性。指出了ATP合成和ATP水解的优先pH区域（分别为pH小于5.4、5.9至6.5以及pH大于6.6、5.5至5.8）。通过电子自旋共振（ESR）技术对自由基含量进行了测量。根据所得结果推测，在ATP合成过程中，归因于ADP自由基的一部分ESR信号增强。
