Different between oxidative phosphorylation and substrate level phosphorylation?
Wiki User
∙ 14y ago
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!
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.
What is the difference between photorespiration and respiration?
photorespiration: RuBP accepts oxygen instead of CO2 during photosynthesis because production of oxygen has exceeded production of CO2. respiration: Oxygen is produced in oxidative phosphorylation/chemisosmosis and used to produce water during respiration.
What is function of midpiece of sperm cell?
Middle piece is formed of mitochondiral spiral , nebenkern around the proximal part of axoneme. The mitochondria are the carriers of the oxidative enzymes and the enzymes which are responsible for oxidative phosphorylation. So the middle piece is the power house of a sperm
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.

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.

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.
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.

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.
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.
What is released when a chemical bond is broken between the second and third phosphate of an ATP molecule?
It isn't. AMP (adenosine monophosphate) remains intact but has no chemical energy to give and it is not broken off. It must be reenergized in the portion of cellular respiration called oxidative phosphorylation, where it goes to ADP (a-diphosphate) and finally to ATP (a-triphosphate), which is as high as the molecule can go and remain stable.
What is differential medium?
A single substrate that discriminates between group[s of microorganisms on the basic of differences in their appearance due to different chemical reactions.
