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).

edited and simplified by Holy122 :P
Phosphorylation is a biochemical process that involves the addition of a phosphate group to a molecule, typically a protein, to regulate its function, activity, or localization within the cell. This modification alters the structure and function of the target molecule, often serving as a key mechanism for cellular signaling and control of various cellular processes.

What type of phosphorylation does not require a membrane?
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.
What is the definition of glycolysis?
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
Will phosphorylation denature a protein?
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.
What are two methods of phosphorylation?
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.
What does phosphorylation do to a moleclue?
it adds a phosphate group Phosphorylation is the addition of a phosphate (PO43−) group to a protein or other organic molecule.

What is the attachment of a phosphate group to a molecule called?
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.

In fermentation is ATP produced by substrate level phosphorylation or oxidative phosphorylation or both or neither?
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.
What does phosphorylation do to a moleclue?
it adds a phosphate group Phosphorylation is the addition of a phosphate (PO43−) group to a protein or other organic molecule.
Substrate level phosphorylation accounts for approximately what percentage of ATP formed during glycolysis?
Substrate-level phosphorylation accounts for approximately 10% of the ATP formed during glycolysis.
What is the opposite of oxidative phosphorylation?
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.
Different between oxidative phosphorylation and substrate level 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?
Substrate-level phosphorylation is a metabolic process in which a phosphate group is transferred from a substrate molecule to ADP, forming ATP directly. This occurs in pathways such as glycolysis and the citric acid cycle, where enzymes catalyze the transfer of the phosphate group. It differs from oxidative phosphorylation, which involves the electron transport chain and ATP synthase to generate ATP.
Another name for electron transport chain is?
The electron transport chain is also known as the respiratory chain.
