Oxidative phosphorylation occurs in order to produce energy in the form of ATP.
It occurs after chemiosmosis, in which a concentration gradient of hydrogen ions is created in the mitochondria between the matrix and the intermembrane space.
As the hydrogen ions flow across this gradient, ADP and Pi are combined and ATP is produced.
Hope this helps!
Oxidative phosphorylation is a process in which most ATPs are produced in cellular respiration. The purpose of oxidative phosphorylation is to turn ADP back into ATP.
oxidative phosphorylation in cellular respiration
ATP is produced by substrate level phosphorylation during glycolisis. There is no oxidative phosphorylation in fermentation since it's an anaeorobic respiration.
The opposite of phosphorylation is dephosphorylation. Source: http://en.wikipedia.org/wiki/Dephosphorylation
The passing on of excited electrons from protein to protein. This is known as the electron transport chain that occurs in the inner membrane of the mitochondrion.
Krebs cycle and oxidative phosphorylation
It is the final electron acceptor is the oxidative phosphorylation pathway.

Mitochondria
Oxidative phosphorylation is necessary for most metabolic function. It is highly efficient and the primary means by which ATP is produced, which provides the energy for metabolism.
Yes, Wikipedia does offer in depth information on Oxidative Phosphorylation. They break it down into many parts and have several diagrams to explain what it is.
Cell membrane
ATP is created by the movement of protons back into the mitochondrial matrix through complex V which is ATP synthase. The effect that electron transport has on oxidative phosphorylation is that the two processes are tightly coupled, stopping electron transport will ultimately stop oxidative phosphorylation.
