细胞能量代谢的最重要过程三羧酸循环和氧化磷酸化均在线粒体中进行,因此线粒体常被比作细胞的动力工厂。但在提供能量的同时线粒体亦会生成活性氧(ROS)等副产品,特别是伴随着运动应激,线粒体处于高NADH、高氧状态,其电子传递链上的氧化还原酶也处于高还原状态,引起ROS生成大幅 The most important process of cell energy metabolism, the tricarboxylic acid cycle and oxidative phosphorylation are all carried out in the mitochondria, so the mitochondria are often compared to the cell’s power plant. However, while supplying energy, mitochondria also generate by-products such as reactive oxygen species (ROS). Especially with exercise stress, mitochondria are in high NADH and hyperoxia state, and oxidoreductases in their electron transport chains are also in a highly reduced state, Cause ROS to generate substantial
