摘要
pH-dependence of initial (admixtural) adenosine triphosphate (ATP) changes (ATP synthesis and hydrolysis) was studied for aerated and desaerated 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 < pH 5.4, 5.9 divided-by pH 6.5 and pH > 6.6, pH 5.5 divided-by 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.
