Recductive phosphorylation is the opposite of oxidative phosphoroylation. Reductive phosphorylation will occur in photosynthesis, when the chemiosmotic gradient is created because proteins along the thylakoid membrane have channeled hydrogen ions from the stroma to the thylakoid space. After, the hydrogen ions want to go back into the stroma because of the chemiosmotic gradient, and therefore, the enzyme ATP Synthase will open and let them run through. Like a wind turbine, it will spin at the same time, and crush ADP and P to make adenosine triphosphate (ATP). This whole process as a whole is called reductive phosphorylation because it essentially is one of the steps in reducing (giving electrons) carbon dioxide to glucose.

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 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 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.
Another word for respiration?
Chemiosmotic phosphorylation
Why fire is blue in color?
the fire has two flames.the upper oxidative flame and the lower reductive flame.the reductive flame seems to blue because of hydrogen.
Is hawks eat mice deductive or inductive reasoning?
reductive
Which process changes matter into one or more substance?
Depends on the "matter".. Generally a process which turns a single substance into two or more parts is called "Reduction" or "reductive". Some, but not all, chemical reactions are reductive of molecules. But wielding an axe is reductive of trees, and slamming an atom with high powered neutrons is reductive of atomic nuclei ("fission"). Processes opposite of "reduction" include (covalent) "bonding", nuclear "fusion", "crystallization" and (in biology, e.g.) "growth" and "emergence".
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.
Why is reductive division and old name for meiosis?
As it results in reduction in genetic content of cells
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.
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.
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.
What is the mechanism of ozonolysis with reductive work-up and how does it contribute to the overall transformation of organic compounds?
Ozonolysis with reductive work-up involves breaking carbon-carbon double bonds in organic compounds using ozone, followed by reduction with a reagent like zinc or dimethyl sulfide. This process creates carbonyl compounds, which are useful intermediates for further chemical reactions. Overall, ozonolysis with reductive work-up helps in the structural elucidation and functional group transformations of organic compounds.
What are the different types of phosphorylation and where do they occur?
Phosphorylation primarily occurs in two forms: substrate-level phosphorylation and oxidative phosphorylation. Substrate-level phosphorylation occurs in the cytoplasm during glycolysis and in the mitochondria during the citric acid cycle, where ATP is produced directly from a substrate. Oxidative phosphorylation takes place in the inner mitochondrial membrane, involving the electron transport chain and chemiosmosis, where ATP is generated indirectly through the flow of protons across the membrane. Additionally, there is protein phosphorylation, which is a regulatory mechanism occurring in various cellular locations, including the cytoplasm and nucleus, where proteins are modified by the addition of phosphate groups, often impacting their activity and function.
