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).

Unlike oxidative phosphorylation, in substrate level phosphorylation the oxidation and phosphorylation are not coupled.
See related questions, "What is oxidative phosphorylation" and "What is substrate-level phosphorylation" below for individual explanations.
Substrate-level phosphorylation and oxidative phosphorylation.
Cellular respiration. But to be more specific, the process is known as phosphorylation. There are three kinds of phosphorylation: the substrate-level phosphorylation, oxydative phosphorylation and photophosphorylation.
ATP is produced by substrate level phosphorylation during glycolisis. There is no oxidative phosphorylation in fermentation since it's an anaeorobic respiration.
Phosphorylation of AMP yields ADP (and ATP if you do it again).
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.
An advantage of the phosphorylation cascade is that is can be helpful to regulate the activation of proteins.

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.
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).
substrate level phosphorylation does not involve (electron transport chain), oxidative phosphorylation does. Substrate level phosphorylation involves the direct transfer of phosphate from a phosphate bearing molecule to ADP, thus yielding ATP. In cellular respiration, oxidative phosphorylation requires a protein, ATP synthase, to channel energy provided by a concentration of H ions; this energy results in the combining of phosphate with ADP.
oxidative phosphorylation takes place in cytosol region and then move on to mitochondira
Its a process which generates ATP using substrate level phosphorylation. This process is anaerobic (does not need oxygen) and generates two net ATP per molecule of glucose
Substrate Level Phosphorylation does not depend on the Electron Transport Chain while Chemiosmosis does. Substrate Level Phosphorylation does not need Oxygen for it to occur while Chemiosmosis requires Oxygen. Also, Chemiosmosis produces more ATP than Substrate Level Phosphorylation.
No, phosphorylation is the addition of a phosphate group.
The key idea of phosphorylation is to add a phosphate to ADP to create ATP molecules, which the cell can use for energy.
