Photophosphorylation光合磷酸化
Photophosphorylation refers to the use of light energy from photosynthesis to ultimately provide the energy to convert ADP to ATP, thus replenishing the universal energy currency in living things. 光合磷酸化是指利用光合作用中的光能,最终将ADP转化为ATP,从而补充生物体中的通用能量货币。
In the simplest systems in prokaryotes, photosynthesis is used just for the production of energy, and not for the building of any biological molecules. In these systems there is a process called cyclic photophosphorylation which just accomplishes the ADP to ATP process for immediate energy for these cells. 在原核生物中最简单的系统中,光合作用仅用于产生能量,而不用于合成任何生物分子。在这些系统中,有一种称为环式光磷酸化的过程,它仅完成ADP到ATP的转化,为这些细胞提供即时的能量。
Photophosphorylation in ordinary plants is a much more ambitious undertaking. In the process called noncyclic photophosphorylation, a plant must accomplish the splitting of water, the conversion of ADP to ATP, and the provision of the reduced coenzyme NADPH to power the synthesis of energy storage molecules. 在普通植物中,光合磷酸化是一个更为雄心勃勃的进程。在称为非循环光合磷酸化的过程中,植物必须完成水分的分解、ADP转化为ATP,以及向合成能量储存分子提供还原型辅酶NADPH。
