通过昼夜周期振荡（生理时钟），细胞交替地进入两个周期部分，其性质在数量和质量上都不同。每个部分持续大约11到13个小时。这种振荡的基本重要性在于这样一个事实，即细胞因此被带到某些极端的生理状态。各种生理功能只有在达到这些极限时才有可能。这些极端状态之一的特征在于高合成能力，另一个特征在于高分解代谢能力。我们可以用一张图（图1）来说明振荡器对细胞化学反应的重要性。
By means of diurnally periodic oscillations (the physiological clock) the cell is brought alternately into two period parts with properties differing both quantitatively and qualitatively. Each of these parts lasts approximately eleven to thirteen hours. The basic importance of this oscillation lies in the fact that the cell is thus brought to certain extreme physiological states. Various physiological functions are possible only when these extremes are reached. One of these extreme states is characterized by a high synthetic capacity and the other by a high catabolic capacity. We may illustrate the importance of the oscillator for cellular chemical reactions by means of a diagram (Fig. 1).
