The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS).
Which part of cellular respiration produces the most ATP quizlet?
The glycolysis stage is responsible for producing most of the ATP during cellular respiration.
Which pathway produces the most ATP?
Oxidative phosphorylation is the metabolic pathway that produces the most ATP. It is a part of the cellular respiration process. The energy required to drive oxidative phosphorylation comes from oxidation-reduction reactions.
Where does the ATP produced in cellular respiration come from?
Cellular respiration is a metabolic pathway that uses glucose to produce adenosine triphosphate (ATP), an organic compound the body can use for energy. One molecule of glucose can produce a net of 30-32 ATP.
What part of cellular respiration produces the most ATP Related Questions
Which part of ATP contains the most energy?
The phosphate tail of ATP is the actual power source which the cell taps. Available energy is contained in the bonds between the phosphates and is released when they are broken, which occurs through the addition of a water molecule (a process called hydrolysis).
Which system produces the most ATP quizlet?
Which step in cellular respiration produces the most ATP? The electron transport chain.
Is the majority of ATP produced by substrate level phosphorylation?
Most ATP is generated by oxidative phosphorylation in aerobic or anaerobic respiration while substrate-level phosphorylation provides a quicker, less efficient source of ATP, independent of external electron acceptors. This is the case in human erythrocytes, which have no mitochondria, and in oxygen-depleted muscle.
Which part of a cellular respiration produces the most NADH?
There are three main steps of cellular respiration: Glycolysis. The citric acid cycle, which makes the most NADH.
Where is ATP generated in mitochondria?
In conclusion, the vast majority of the ATP produced from the oxidation of glucose in an animal cell is produced by chemiosmotic mechanisms in the mitochondrial membrane.
Where is ATP produced in electron transport chain cellular respiration?
The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.
Where does ATP come from in mitochondria?
Most of the adenosine triphosphate (ATP) synthesized during glucose metabolism is produced in the mitochondria through oxidative phosphorylation. This is a complex reaction powered by the proton gradient across the mitochondrial inner membrane, which is generated by mitochondrial respiration.
Which energy system provides most ATP at rest Why?
This system is called the oxidative system. The Oxidative system– This system is the primary source of ATP at rest and during low-intensity activities. The body uses mainly carbohydrates and fats during this system. At rest you are mainly using fats compared to the carbohydrates until the intensity increases.
Is the majority of ATP produced in the electron transport chain?
Explanation: The electron transport chain generates the most ATP out of all three major phases of cellular respiration. Glycolysis produces a net of 2 ATP per molecule of glucose. In the Krebs cycle, there is one GTP (which is an ATP equivalent) generate in the conversion of succinyl-CoA to succinate.
Where is majority of ATP synthesized in oxidative phosphorylation?
Most of the usable energy obtained from the breakdown of carbohydrates or fats is derived by oxidative phosphorylation, which takes place within mitochondria.
How much ATP is produced in glycolysis?
During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi –> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation.
Where does the most energy come from in cellular respiration?
Glucose is the main source of energy for cellular respiration regardless of what kind of organism it is undergoing this ATP-producing metabolic process.
Where is most of the energy in cellular respiration?
Answer and Explanation: Most of the ATP energy obtained from cellular respiration is produced in the third and final stage, the electron transport chain. In the electron transport chain, electrons are passed from one acceptor to the next, in a series of redox reactions.
Which form of cellular respiration releases the most energy?
Aerobic respiration produces about 19 times more energy than anaerobic respiration per glucose molecule.
Is the ATP in the mitochondria?
‚ÄãMitochondria Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Where is ATP made in chloroplast?
The chloroplast adenosine triphosphate (ATP) synthase is located in the thylakoid membrane and synthesizes ATP from adenosine diphosphate and inorganic phosphate at the expense of the electrochemical proton gradient formed by light-dependent electron flow.
