许多生物体会对光照的变化做出反应。他们开发了感觉系统，其中光的吸收触发由代谢反应驱动的细胞过程的变化，例如眼睛光感受器中跨膜电流的变化。细胞在信号转导中消耗能量。相反，在能量转导过程中，吸收的光能被转换为其他形式的能量，细胞利用这些能量来驱动新陈代谢过程。直到最近，已知的唯一生物能量转换系统是植物和真细菌的光合作用，它使用叶绿素作为能量转换色素。大约 15 年前，第二个完全不同的系统被发现于
Many organisms react to changes in illumination; they have developed sensory systems in which the absorption of light triggers changes in cellular processes driven by metabolic reactions, eg the changes of transmembrane currents in the photoreceptors of the eye. The cells expend energy in signal transduction. In contrast, during fight energy transducfion, the absorbed light energy is converted to other forms of energy which the cells use to drive metabolic processes uphill. Until recently, the only biological, fight energy-transducing system known was the photosynthesis of plants and eubacteria, which uses chlorophyll as the energy-converting pigment. About 15 years ago, a second, quite different system was discovered in
