Abstract

The ATP release from "caged" ATP by laser flash was determined at different temperatures and pH values. We measured the time resolved absorbance changes of the coloured intermediate, which is involved in the photolytic process. The linearity of the Arrhenius curves suppose only one process and the calculated activation enthalpies (around 55 kJ/mole) did not change markedly at the pH values of 6.0, 7.0 and 8.0

笼中ATP释放的温度依赖性。
在不同的温度和pH值下,测定了激光照射下“笼状”ATP的释放量。我们测量了参与光解过程的有色中间体的时间分辨吸光度变化。Arrhenius曲线的线性只假设一个过程,在pH值为6.0、7.0和8.0时,计算的活化焓(约为55 kJ/mol)没有明显变化
