Photophosphorylation differs from oxidative phosphorylation in that?
Wiki User
∙ 11y ago
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.

What is the process of converting energycfrom a light -excited electron into pyrophosphate bond of an ADP molecule?
Most probably it is the substrate-level phosphorylation.
Which is NOT a pathway in the oxidation of glucose?
gluconeogenisis. what is part of it: Glycolysis, Krebs cycle, and the ETC and oxidative phosphorylation.
What 2 main parts are made up in oxidative phosphorylation?
Electric transport chain and chemiosmosis
Substrate level phosphorylation accounts for approximately what percentage of ATP formed during glycolysis?
100%. Substrate level phosphorylation accounts for about 10% of ATP generated by respiration. The other 90% is generated by oxidative phosphorylation.
By which mechanism does azide kill bacteria?
Azide blocks cytochrome c oxidase, preventing the generation of ATP by oxidative phosphorylation.
Photophosphorylation is most similar to?
oxidative phosphorylation in cellular respiration
Compare and contrast photophosphorylation and oxidative phosphorylation?
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.
ATP can convert to ADP during what?
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).
Another name for electron transport chain is?
oxidative phosphorylation
In glycolysis ATP molecules are produced by .?
In glycolysis, ATP molecules are produced by? a- oxidative phosphorylation b-substrate-level phosphorylation c-cellular respiration d-photophosphorylation e-photosynthesis
What type of phosphorylation does not require a membrane?
oxidative phosphorylation
In fermentation is ATP produced by substrate level phosphorylation or oxidative phosphorylation or both or neither?
ATP is produced by substrate level phosphorylation during glycolisis. There is no oxidative phosphorylation in fermentation since it's an anaeorobic respiration.
What stage produces the most ATP when glucose is completely oxidized to carbon dioxide and water?
oxidative phosphorylation
What is the opposite of oxidative phosphorylation?
The opposite of phosphorylation is dephosphorylation. Source: http://en.wikipedia.org/wiki/Dephosphorylation
Where does oxidative phosphorylation take place in a eukaryote?
Mitochondria
Energy released by electrons is often used to phosphorylate?
Adenosine triphosphate, or ATP, is the most common source of energy in cells, and is created through phosphorylation. This can be photophosphorylation (as occurs in photosynthesis) or substrate level phosphorylation, or oxidative phosphorylation. ATP is created by adding a phosphate group to ADP (adenosine diphosphate), so the answer to your question would be that the energy is used to phosphorylate ADP, turning it into ATP.
Does Wikepedia offer in depth information on Oxidative Phosphorylation?
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.
