The electron transfer in the photosynthetic membrane of green plants from H2O to NADP+ is driven by two chlorophyll reaction centers in series. The electron transfer converts one part of the light energy into the form of the reducing power of NADPH. The transfer initiates an electrical field across the membrane. The electrical energy of the charged membrane is an additional state into which light energy is converted. Protolytic reactions coupled with the electron transfer lead to a proton translocation into the inner space of the thylakoid. The discharging of the ectrically energized membrane by H+ efflux is coupled with the formation of ATP.
绿色植物光合膜中从H₂O到NADP⁺的电子传递由两个串联的叶绿素反应中心驱动。电子传递将一部分光能转化为NADPH还原力的形式。这种传递引发了跨膜电场。带电膜的电能是光能转化进入的另一种状态。与电子传递耦合的质子反应导致质子转运到类囊体内部空间。通过H⁺外流使带电膜放电与ATP的形成相耦合。
