摘要

Membrane-bound electron transfer systems, such as NADH dehydrogenase, the bc₁ complex, and cytochrome oxidase, conserve energy from oxidation-reduction reactions as a transmembrane gradient of protons. Some of these protons move directly with electron transfer; others appear to be pumped separately. Although we now have a clear picture of the sequence for electron transfer in cytochrome bc₁ complexes, the mechanisms of linkage to proton flow are only beginning to emerge. This is a fundamental area for continued research in bioenergetics.

膜结合电子传递系统，例如NADH脱氢酶，bc 1复合物和细胞色素氧化酶，作为质子的跨膜梯度保存来自氧化还原反应的能量。这些质子中的一些直接与电子转移一起移动;其他人似乎是分开抽水的。虽然我们现在清楚地了解了细胞色素bc 1复合物中电子转移的序列，但质子流的连接机制才刚刚开始出现。这是继续研究生物能学的一个基础领域。
