What is the difference between substrate level phosphorylation and chemiosmosis?

substrate level phosphorylation does not involve (electron transport chain), oxidative phosphorylation does. Substrate level phosphorylation involves the direct transfer of phosphate from a phosphate bearing molecule to ADP, thus yielding ATP. In cellular respiration, oxidative phosphorylation requires a protein, ATP synthase, to channel energy provided by a concentration of H ions; this energy results in the combining of phosphate with ADP.

The electron transport system is the set of proteins and other cellular components that are involved in the electron transport chain.
For example, the both aerobic and anaerobic organisms, there are different electron transport systems and this influences the path electrons take. Therefore they have different electron transport chains.
Whatever the path or system, electron transport serves the same function in all organisms: energy production

Oxidative phosphorylation is the oxidation of nutrients ( stripping electrons ) and using oxygen as the final electron acceptor at the end of the electron transfer chain. As these electrons are transferred the protons that came along for the ride, so to speak, are pumped into the outer membrane of the mitochondria where they come back down the concentration gradient through the ATP synthase to complete the process of the aforementioned chemiomosis.

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.
What is oxidative phosphorylation and what is its purpose?
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!
The relationship between ATP synthase and Chemiosmosis?
chemiosmosis is one of the processes that produces ATP. this happens in the inner membrane of the mitochondria
Explain the difference between substrate and active site?
Substrate is the reactant in which an enzyme reacts out. While the active Site is a special region of the enzyme where the substrate binds forming a temporary enzyme-substrate complex.
Difference of chemiosmosis in chloroplasts and mitochondria?
Well, I know that in mitochondria, protons are pumped from the matrix to the intermembrane space; however, in chloroplasts, protons are pumped from the stroma to the thykaloid space.I am not sure if that is the only difference, though ^^'

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.

The difference between substrate and active site?
substrate goes in the active site. so if you have an ezyme, there would be a region where the substrate would fit into the active site.
The relationship between ATP synthase and Chemiosmosis?
chemiosmosis is one of the processes that produces ATP. this happens in the inner membrane of the mitochondria
What is the relationship between chemiosmosis and ATP formation?
chemiosmosis is one of the processes that produces ATP. this happens in the inner membrane of the mitochondria.
What is the difference between phosphorylase and phosphatase?
Phosphorylase adds the Phosphate group to substrate, but phosphatase takes off the Phosphate group from the substrate. the function of phosphorylase can be considered as same as kinase. they are all playing key roles in the cellular signalling transduction via control the phosphorylation, the phosphatase can be the negative or positive regulator for different pathways. e.g. PTP1B dephosphorylates the JAK2 to suppress leptin in the hypothalamus that contribute to weight gain.
The difference between oxidative phosphorylation and chemiosmotic coupling?
oxidative phosphorylation does not involve with the respiratory complex in the inner mitochondria membrane. Oxidative phosphorylation useful in generate the production of ATP from the proton gradient or proton motive force. Chemiosmotic coupling invilve the manner of ETC on how its create the proton gradient and the proton gradient is indirectly directed with the production of ATP.The proton gradient causes the conformational change of tigthly binding of ATP to open binding ATP .Then ATP can be released and be used to the metabolic cell needs and translocate the ATP to cytoplasm that can be used to phosphorylate substrate.
Explain the difference between substrate and active site?
Substrate is the reactant in which an enzyme reacts out. While the active Site is a special region of the enzyme where the substrate binds forming a temporary enzyme-substrate complex.
What is the difference between substrate and product?
The substrate is the substance (or substances) that attaches to the enzyme's active site before the reaction occurs.The product is the substance (or substances) that is formed after the enzyme has worked on the substrate.///
What is the difference between the lock and key model versus the induced fit model of the enzyme substrate complex?
The lock and key model means that the substrate must perfectly fit the enzyme, and the enzyme does not change. The induced fit model is different as when the substrate fits together with the enzyme, the enzyme itself will change to either join substrates together or break a substrate down.
What is the relationship between substrate concentration and enzyme activity?
At low substrate concentrations, the rate of enzyme activity is proportional to substrate concentration. The rate eventually reaches a maximum at high substrate concentrations as the active sites become saturated.
