Substrate oxidative phosphorylation refers to the process in which ATP is generated in the mitochondria through the transfer of electrons from reduced substrates to oxygen via the electron transport chain. This process generates a proton gradient across the inner mitochondrial membrane, which is then used by ATP synthase to produce ATP from ADP and inorganic phosphate.
What else can I help you with?
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.
What term describes reactants when they associated with enzymes?
if you mean what do you call the substance that an enzyme works on then that's called a substrate
What is the substrate name for papain?
The substrate of protease is a peptide bond.
Where does an enzymes join with a substrate?
The enzyme substrate complex
How does using substrate modifier change the composition of the substrate?
Using substrate modifiers can alter the chemical structure or properties of the substrate by introducing functional groups that can interact with the substrate through chemical bonds. This can change the reactivity, selectivity, or stability of the substrate, leading to different reaction pathways or products.
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.
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.
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 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.
What is Aquarium Sand?
You mean substrate?
What term describes reactants when they associated with enzymes?
if you mean what do you call the substance that an enzyme works on then that's called a substrate
What is the function of dehydrogenase?
Dehydrogenase enzymes catalyze the removal of hydrogen atoms from a substrate molecule. This is an important step in various metabolic processes as it helps in transferring electrons and energy between molecules.
Which three substances must be presented in mitochondria for the process of aerobic respiration to take place?
Oxygen is needed as the final acceptor of electrons in the electron transport chain, glucose is the starting substrate for producing ATP through glycolysis and the citric acid cycle, and ADP is needed as a substrate to be phosphorylated to form ATP in oxidative phosphorylation.
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.///
The binding together of an enzyme and a substrate forms a what?
enzyme-substrate complex
Description of oxidative enzymes?
Oxidative enzyme is an enzyme that catalyzes the reaction of oxides. There are two types of oxidative enzymes, which are the peroxidases and oxidases.
What to enzymes do in an enzyme-substrate?
in an enzyme-substrate complex, the enzyme acts on the substrate .
