WebThe four major classes of electron carriers involved in both eukaryotic and prokaryotic electron transport systems are the cytochrome s, flavoprotein s, iron-sulfur protein s, and the quinone s. In aerobic respiration , the final electron acceptor (i.e., the one having the most positive redox potential) at the end of the ETS is an oxygen ... WebThe electron traveling to the Reiske Center is transferred to cytochrome c 1 and then onto the attached cytochrome c, which is then released to migrate to Complex IV.
