Describe how is ATP produced by substrate-level phosphorylation?
ATP is produced by substrate-level phosphorylation when a phosphate group is transferred directly from a substrate molecule to ADP to form ATP. This process occurs during glycolysis and the citric acid cycle, where high-energy phosphate bonds are formed to drive ATP synthesis.
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.
Substrate level phsophorylation in cellular respiration?
Substrate-level phosphorylation is a process in cellular respiration that generates ATP directly from a phosphorylated substrate during specific biochemical reactions. It occurs in both glycolysis and the citric acid cycle (Krebs cycle), where a phosphate group is transferred from a substrate to ADP, forming ATP. This mechanism contrasts with oxidative phosphorylation, which relies on the electron transport chain and chemiosmosis. Substrate-level phosphorylation provides a quick source of ATP, particularly in anaerobic conditions.
Type of respiration that does not require oxygen.?
This is anaerobic respiration, also called fermentation or substrate level phosphorylation
Which of these processes is used to make the ATP produced by glycolysis?
The process used to make ATP produced by glycolysis is oxidative phosphorylation, which occurs in the mitochondria. This involves the electron transport chain and ATP synthase, where the electrons generated by glycolysis are used to generate ATP.
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.
Describe how is ATP produced by substrate-level phosphorylation?
ATP is produced by substrate-level phosphorylation when a phosphate group is transferred directly from a substrate molecule to ADP to form ATP. This process occurs during glycolysis and the citric acid cycle, where high-energy phosphate bonds are formed to drive ATP synthesis.
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.
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.

How many ATP molecules are made from substrate-level Phosphorylation?

In what two processes is ATP formed by substrate- level phosphorylation?
ATP is formed by substrate-level phosphorylation during glycolysis and the Krebs cycle in cellular respiration. In both processes, a phosphate group is transferred from a substrate molecule directly to ADP to form ATP.
The transfer of a phosphate group that occurs in glycolysis is called?
The transfer of a phosphate group that occurs in glycolysis is called substrate-level phosphorylation. This process involves the direct transfer of a phosphate group from a substrate molecule to ADP to form ATP.
