【評論內容】Cytochrome c is a small heme-containing protein that is often involved in electron transport in mitochondria and bacteria. It is known to transfer electrons from complex III to complex IV, which is the final electron acceptor in the electron transport chain and reduces molecular oxygen to water. Fe-S and 2Fe-2S clusters are also involved in electron transport, but they do not directly transfer electrons to oxygen. Coenzyme Q transfers electrons to complex III but does not interact with oxygen directly.
