线粒体和叶绿体中能量转化问题研究

Study on the Transformation of Energy in Mitochondria and Chloroplasts

该研究探讨了在线粒体和叶绿体中质子驱动力和三磷酸腺苷(ATP)生成的关系。质子驱动力是驱动ATP生成最直接的因素。结合线粒体内膜的电子传递链系统和叶绿体内囊体膜上的光合系统,分析了线粒体内膜电子传递链、ATP合成酶以及叶绿体内囊体光反应和暗反应的能量转化机制,并且对线粒体和叶绿体系统中的能量转化效率问题进行了定量计算。

The relationship between PMF and ATP generation in mitochondria and chloroplasts was discussed. PMF is the most direct factor of ATP generation. Combined with the mitochondrial electron transport chain system and photosynthetical system on chloroplast thylakoid membrane, energy transformation mechanism of mitochondrial electron transport chain, ATPase, and light reaction and dark reaction of chloroplast thylakoid were analyzed. Energy conversion efficiency of mitochondrion and chloroplast were quantitatively calculated.
