Which couple has minimum redox potential?
NAD+/NADH has minimum redox potential NADH has minimum redox potential Oxygen has maximum redox potential As you go ahead in ETC , redox potential increases i.e Complex I < Complex II < Coenzyme Q < Complex III Fig.: A flowcha showing redox pairs with increasing redox potential. Redox Pair consists of two components- one is oxidized and other is reduced during electron transfer
