The electron transport system present in the photosynthetic apparatus and respiratory chain were evolutionary acquisitions that allowed the organisms to convert electromagnetic energy in chemical energy and thus improve the use of energy fuels. These systems acquired by prokaryotes were preserved in the highly complex organisms always with the participation of the cytochromes. Since the discovery of the cytochromes, and the isolation and association of these proteins to model membranes, the liposomes, have been used to investigative strategies to characterize the structure and function of these proteins. From these studies important findings have contributed to the comprehension of the energy transduction mechanisms and the role played by the nonredox subunits present in the protein complexes of the respiratory chain of eukaryotes.

脂质体中呼吸细胞色素的结合：研究呼吸链的有效策略

存在于光合作用装置和呼吸链中的电子传输系统是进化获得的，它允许生物体将电磁能转化为化学能，从而改善能源燃料的使用。这些由原核生物获得的系统在高度复杂的生物体中始终存在细胞色素的参与。自从发现细胞色素以及这些蛋白质与模型膜的分离和结合以来，脂质体已被用于表征这些蛋白质的结构和功能的研究策略。这些研究的重要发现有助于理解能量转导机制以及真核生物呼吸链蛋白质复合物中存在的非氧化还原亚基所起的作用。
