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

摘要

通过激光闪光从“笼状”ATP释放ATP的过程是在不同温度和pH值下测定的。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。阿累尼乌斯曲线的线性关系表明只有一个过程，并且在pH值为6.0、7.0和8.0时计算出的活化焓（约55千焦/摩尔）没有明显变化。
