  1. The Ultrafast Energy Transfer Process in Purple Bacteria Photosynthetic Reaction Center

    紫细菌反应中心中的超快能量传递过程

  2. The Theoretical Studies on the Machanism of the Primary Electron Transfer in the Mutant Photosynthetic Reaction Center

    细菌光合反应中心突变体原初电子转移机理的理论研究

  3. The Photochemical Change in Photosynthetic Reaction Center of Purple Bacterium with Pheophytin Substitution

    紫细菌光合反应中心中细菌脱镁叶绿素被置换后的光化学活性

  4. All the above showed that the light energy conversion efficiency , potential activity of photosynthetic reaction center and the non-photochemical dissipation of excess light energy , which resisted the damage on photosynthetic apparatus of environmental stress , were improved .

    表明外源NO处理一方面提高了光能转换效率和PSⅡ的潜在活性,另一方面增强了过剩光能的非化学耗散,有利于保护光合机构免受环境胁迫的伤害。

  5. Oxygen-evolving photosynthetic organisms contain two types of photosynthetic reaction center , called photosystem ⅰ( PS ⅰ) and photosystem ⅱ ( PS ⅱ) . The PS ⅱ reaction center uses water as a source of electrons , light energy being used to oxidize water to provide protons and oxygen .

    光合放氧生物包括光系统Ⅰ(PSⅠ)和光系统Ⅱ(PSⅡ)两种类型反应中心,光系统Ⅱ反应中心能以水作为电子给体,利用光能氧化水产生质子和氧气。

  6. When plants absorb more light than that can be used for photosynthesis , the excess energy , which is not promptly quenched , can reduce the photosynthetic efficiency and result in photoinhibition , even photooxidative damage to the photosynthetic reaction center .

    然而,大多数情况下植物接受的能量要超过其所能转化的能量,如果过量的光能不及时耗散掉,光合功能会降低,导致光合作用的光抑制,甚至出现光氧化、光破坏。
