Redox= Reduction+ Oxidation
Oxidation is defined as the loss of electrons
Reduction as the gain of electrons.
The electron lost in the oxidation is accepted by an acceptor which is said to be reduced. Thus the oxidation-reduction is a tightly coupled process.
There are two redox pairs NADH/NAD+ and FMN/FMNH2. The redox pairs differ in their tendency to lose or gain electrons.
Definition of Redox Potential (E0)
what is Redox Potential (E0)
The oxidation-reduction potential or, simply, redox potential, is a quantitative measure of the tendency of a redox pair to lose or gain electrons. The redox pairs are assigned specific standard redox potential (E0 volts) at pH 7.0 and 250C
The more negative redox potential represents a greater tendency (of reductant) to lose electrons.
More positive redox potential indicates a greater tendency (of oxidant) to accept electrons.
