The proton gradient caused by the high concentration of protons in the intermembrane space begins another process called chemiosmosis. The protons "want" to diffuse back into the mitochondrial matrix and to a lower concentration. A very special enzyme in the membrane called ATP synthase will take protons and transport them into the matrix. In doing so, energy is released and used to phosphorylate ADP into ATP.
This process of producing ATP differs from substrate-level phosphorylation. See related links and questions below for more information.
It is the process which is an integral part of photosynthesis during which ADP gets converted into ATP with the aid of energy from electrons released during photolysis of water in photosynthesis.
oxidative phosphorylation
oxidative phosphorylation
Phosphorylation. It can be done by direct transfer of phosphate group (substrate-level phosphorylation), by the use of proton gradient (oxidative phosphorylation), or by using sunlight (photophosphorylation).
it adds a phosphate group Phosphorylation is the addition of a phosphate (PO43−) group to a protein or other organic molecule.
The addition of a phosphate group to an organic molecule. Phosphorylation is important for many processes in living cells. ATP is formed during cell respiration from ADP by phosphorylation, as in the mitochondria of eukaryotic cells (oxidative phosphorylation) and the chloroplasts of plant cells (photosynthetic phosphorylation). Phosphorylation also regulates the activity of proteins, such as enzymes, which are often activated by the addition of a phosphate group and deactivated by its removal (called dephosphorylation).simplified for dummies like me : The addition of a phosphate group to a molecule.edited and simplified by Holy122 :P
phosphorylation
oxidative phosphorylation
ATP is produced by substrate level phosphorylation during glycolisis. There is no oxidative phosphorylation in fermentation since it's an anaeorobic respiration.
oxidative phosphorylation in cellular respiration
An advantage of the phosphorylation cascade is that is can be helpful to regulate the activation of proteins.
oxidative phosphorylation
Substrate-level phosphorylation can best be describe as the direct transfer of phosphate from one substrate to another. Oxidative phosphorylation is different from substrate level phosphorylation is that it generates ATP by using a proton motive force.
The opposite of phosphorylation is dephosphorylation. Source: http://en.wikipedia.org/wiki/Dephosphorylation
That transfer is called phosphorylation.

No, phosphorylation is the addition of a phosphate group.
