Dephosphorylation (removing a phosphate)
Cytoplasmic or soluble enzymes can carry out phosphorylation that does not require a membrane. This type of phosphorylation occurs in the cytoplasm or within organelles like the mitochondria and does not involve a membrane-bound protein complex.
Phosphorylation typically does not denature a protein. Phosphorylation is a reversible modification where a phosphate group is added to a protein, often regulating its function, structure, or localization within the cell. However, extreme or incorrect phosphorylation can lead to protein misfolding and dysfunction.
Two methods of phosphorylation are: Enzyme-catalyzed phosphorylation, where enzymes like kinases transfer phosphate groups from ATP to specific proteins. Photo-phosphorylation, which occurs during photosynthesis where light energy is used to convert ADP and inorganic phosphate into ATP.
it adds a phosphate group Phosphorylation is the addition of a phosphate (PO43−) group to a protein or other organic molecule.
The electron transport chain is also known as the respiratory chain.

The attachment of a phosphate group to a molecule is called phosphorylation. This process often occurs in cellular signaling pathways and can change the activity or function of the molecule being modified.

ATP in fermentation is typically produced by substrate-level phosphorylation, which involves the direct transfer of a phosphate group to ADP from a phosphorylated substrate. Oxidative phosphorylation, which involves the use of an electron transport chain to produce ATP, is not generally involved in fermentation.

The opposite of oxidative phosphorylation is not a specific biological process, as it refers to the metabolic pathway that occurs in mitochondria to generate ATP from ADP using oxygen. However, an anaerobic process like fermentation can be considered as an alternative to oxidative phosphorylation.
100%. Substrate level phosphorylation accounts for about 10% of ATP generated by respiration. The other 90% is generated by oxidative phosphorylation.
Substrate-level phosphorylation occurs during Glycolysis and the Kreb's Cycle and involves the physical addition of a free phosphate to ADP to form ATP. Oxidative phosphorylation, on the other hand, takes place along the electron transport chain, where ATP is synthesized indirectly from the creation of a proton gradient and the movement of these protons back accross the membrane through the protein channel, ATP synthase. As the protons pass through, ATP is created.
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 electron transport chain is also known as the respiratory chain.
ATP is produced from substrate level phosphorylation during glycolysis and the citric acid cycle in cellular respiration.
