A model based on our present knowledge of photosynthetic energy transduction is presented. Calculated electric potential profiles are compared with microelectrode recordings of the thylakoid electric potential during and after actinic illumination periods of intermediate duration. The information content of the measured electric response is disclosed by a comparison of experimental results with calculations. The proton flux through the ATP synthase complex is seen to markedly influence the electric response. Also the imbalance in maximum turnover rate between the two photosystems, common to obligate shade plants like Peperomia metallica used in the microelectrode experiments, is clearly reflected in the electric potential profile.
我们提出了一种基于当前光合作用能量转导知识的模型。计算出的电势分布与中间持续时间的光致发光和照光后期间类囊体电势的微电极记录进行了比较。通过将实验结果与计算结果进行比较，揭示了测量电响应的信息量。可以明显看出，通过 ATP 合酶复合物的质子通量对电响应有显著影响。此外，在微电极实验中使用的像胡椒薄荷这样的必需遮荫植物中普遍存在的两个光系统之间的最大周转率失衡也清楚地反映在电势分布中。
