in oxidative phosphorylation, the H+ moved out of the cell using the channel proteins that make up the ETC (electron transport chain) and then they flow back into the mitochondria through the ATP synthase because of the concentration gradient. Photophosphorylation has its H+ ions travelling in the opposite direction (from inside to outside of the chloroplasts through ATP synthase. Another difference is the fact that in photophosphorylation the H+ are produced by splitting water while the H+ in oxidative phosporylation come from H+ that have been removed from compounds and have had their electrons removed by NAD+ or FAD.
Another name for oxidative phosphorylation is electron transport chain.
Both processes are run inside the human body in order to produce energy. Oxidative phosphorylation produces much more energy at a less of an expense than anaerobic glycolysis. It also has energy coming from multiple sources unlike anaerobic glycolysis which only comes from one source.
Most probably it is the substrate-level phosphorylation.
100%. Substrate level phosphorylation accounts for about 10% of ATP generated by respiration. The other 90% is generated by oxidative phosphorylation.
Oxygen is the final electron acceptor of the electron transport chain in oxidative phosphorylation. It accepts electrons from complex IV (cytochrome c oxidase) and combines with hydrogen ions to form water.
Photophosphorylation is most similar to oxidative phosphorylation in that it involves the production of ATP through a series of redox reactions that generate a proton gradient across a membrane. However, in photophosphorylation, the energy for driving the process is derived from light instead of the oxidation of organic molecules.
Oxidative phosphorylation is ATP synthesis driven by electron transfer to oxygen and photophosphorylation is ATP synthesis driven by light. Oxidative phosphorylation is the culmination of energy-yielding metabolism in aerobic organisms and photophosphorylation is the means by which photosynthetic organisms capture the energy of sunlight, the ultimate source of energy in the biosphere.
The electron transport chain is also known as the respiratory chain.
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.
Mitochondria
Yes, oxidative phosphorylation is a vital part of cellular metabolism as it produces the majority of ATP in aerobic organisms. ATP is the primary energy source for cellular processes, making oxidative phosphorylation crucial for overall metabolism function.
Another name for oxidative phosphorylation is electron transport chain.
Yes, Wikipedia does offer in depth information on Oxidative Phosphorylation. They break it down into many parts and have several diagrams to explain what it is.
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.
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.
Cell membrane
Oxidative phosphorylation occurs in order to produce energy in the form of ATP. It occurs after chemiosmosis, in which a concentration gradient of hydrogen ions is created in the mitochondria between the matrix and the intermembrane space. As the hydrogen ions flow across this gradient, ADP and Pi are combined and ATP is produced. Hope this helps!
