In a sequence of flashes given to dark-adapted chloroplasts, the flash yield of proton release oscillates with a period of 4, which is similar but not identical to the oscillation of the O2 flash yield. 2. Using the proton release associated with ferricyanide reduction as a calibration, we computed that two protons are released in the terminal O2-liberating reaction; the other two protons are released in precursor conversion steps. 3. Analysis of the effect of preflashes on the oscillation pattern showed that the S1 leads to S2 transition releases no proton, the S0 leads to S1 transition somewhat less than one (0.75), and the S2 leads to S3 transition somewhat more than one (1.25). 4. The precision of the data was sufficient to exclude the possibility that in the four-step water oxidation, proton release follows a simple 1, 0, 1, 2 pattern. A possible model to interpret the observed flash yield patterns is discussed.

在给予暗适应叶绿体的一系列闪光中，质子释放的闪光产额以4的周期振荡，这与O2闪光产额的振荡相似但不完全相同。2. 以与铁氰化物还原相关的质子释放作为校准，我们计算出在最终的O2释放反应中有两个质子被释放；另外两个质子在前体转化步骤中被释放。3. 对预闪光对振荡模式影响的分析表明，S1到S2的转变不释放质子，S0到S1的转变略少于一个（0.75），S2到S3的转变略多于一个（1.25）。4. 数据的精度足以排除在四步水氧化过程中质子释放遵循简单的1、0、1、2模式的可能性。讨论了一个可能解释观察到的闪光产额模式的模型。
