An electron transport chain (ETC ) is a series of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors via redox reactions (both reduction and oxidation occurring simultaneously) and couples this electron transfer with the transfer of protons (H ions) across a membrane. The electrons that transferred from NADH and FADH2 to the ET… WebA generalized scheme of the electron transport system in chemotrophic microorganisms is depicted in Fig. 1.1.In this system, the first molecule in the electron chain is typically NAD or NADP. Enzymes, called dehydrogenases, remove electrons and hydrogen ions from substrates and many dehydrogenases use the pyridine nucleotides (NAD) nicotinamide …
