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
Glycolysis and Citric Acid Cycle (Krebs Cycle) form ATP directly in the Substrate Level of Phosphorylation
Phosphorylation and oxidation
oxidative phosphorylation
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
Phosphorylation takes place in the inner mitochondrial membrane. The Krebs cycle takes place in the mitochondrial matrix. The electron transport chain contains three complexes and two mobile carriers.
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.
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.
