The electron transport chain (ETC) is a crucial process in cellular respiration, occurring in the mitochondria of eukaryotic cells. It is the final step in the process of extracting energy from nutrients and plays a vital role in the generation of adenosine triphosphate (ATP), the primary energy currency of cells. In this article, we will delve into the details of the electron transport chain, its components, and its significance in cellular energy production.
