WebIron-sulfur centers, having low redox potential, are found in early part of chain such as in NADH dehydrogenase complex. Heme groups, whose iron atoms are used as electron carriers, give cytochromes their color. Describe relationship b/w protons and electrons in oxidation/reduction and how it is used to drive protons across membrane. WebMetals with a positive redox potential are called noble metals. Metals with a negative redox potential are called base metals. Redox potential values (under certain standard conditions) are fixed and can be found in tables like this one. For example, the redox potential of silver (Ag) is +0.7994 V and the redox potential of zinc (Zn) is ‑0.763 V.
WebThe redox potential is a molecular property in chemistry that is very important for renewable energy problems. It measures the tendency of a species to gain or lose electrons in solution. In order to apply computational chemistry to renewable energy problems, being able to compute redox potentials for molecular species is incredibly important.
