Oxidative Phosphorylation. It is the process by which electrons are carried from reduced cofactors (NADH + / QH 2 ) are finalled in stepwise manner to oxygen. Electrons flow much like electricity in a circuit with free energy being conserved with the formation of proton gradient.

Electrons flow much like electricity in a circuit with free energy being conserved with the formation of proton gradient.
In the end the investment of reduced cofactors are utilized in the production of ATP
Reduced cofactors like NADH+ are produced during glycolysis, Citric acid cycle and fatty acid oxidation
During cellular respiration oxidative phosphorylation chemical energy of these reduced molecules are utilized to produce ATP
The ultimate acceptor of e- through a series of O/R reactions is the O2 within the mitochondrion
In simple outline, ETC involves the removal of hydrogen atoms from the oxidizable substrates; these hydrogen atoms enter the ETC, a system of membrane – bound complexes and each soon split to yield a proton and electron. These electrons then pass through a series of cytochromes, finally reacting with molecular oxygen and the protons that were released earlier, to form water
NADH + H++ Q NAD+ + QH2
Complex I – k/as proton pump driven by the energy of electron transfer; where – protons move from one location (matrix which then becomes negatively charged) to the other (intermembrane space which becomes positively charged)
Fatty acyl CoA
