What part of respiration makes the most ATP?
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.
What produces ATP the most?
So, oxidative phosphorylation is the metabolic cycle that produces the most net ATP per glucose molecule.
Where is most of the ATP produced?
The majority of ATP synthesis occurs in cellular respiration within the mitochondrial matrix: generating approximately thirty-two ATP molecules per molecule of glucose that is oxidized.
Why does etc produce the most ATP?
Electron transport chain produces an electrochemical gradient, which facilitates the synthesis of ATP by ATP synthase by chemiosmosis.
Which process produces the most ATP quizlet?
Most of the ATP in cellular respiration is produced by the process of chemiosmosis.
Which part of cellular respiration produces the most ATP and how does it work?
The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS) present in mitochondria. The formation of ATP occurs by oxidative phosphorylation.
Which form of respiration produces more energy?
Advantages of Aerobic Respiration
With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.
Which step of aerobic respiration generates the most ATP quizlet?
Most of the ATP produced in cellular respiration come from oxidative phosphorylation, in which the energy released from redox reactions in an electron transport chain is used to produce ATP. In substrate level phosphorylation, an enzyme dirctly transfers a phosphate group to ADP fro an intermediate substrate.
What part of cellular respiration produces the most NADH?
citric acid cycle
Glycolysis. The citric acid cycle, which makes the most NADH.
Which process produces more energy?
Summary. Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose.
Why does aerobic respiration produce more ATP?
Aerobic respiration produces more ATP than anaerobic respiration due to the complete oxidation of glucose to CO2 and water. O2 acts as the terminal electron acceptor in the electron transport chain and gets reduced to water. Most of the ATPs are produced by oxidative phosphorylation in the electron transport chain.
Does anaerobic or aerobic respiration produce more ATP?
Anaerobic cell respiration (glycolysis + fermentation) produces 2 ATP/glucose consumed. Aerobic cell respiration (glycolysis + the Krebs cycle + respiratory electron transport) produces 36 ATP/glucose consumed. Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration.
How much ATP is produced in each step of cellular respiration?
How much ATP is produced in all three stages combined? Glycolysis produces 2 ATP molecules, and the Krebs cycle produces 2 more. Electron transport from the molecules of NADH and FADH2 made from glycolysis, the transformation of pyruvate, and the Krebs cycle creates as many as 32 more ATP molecules.
How many ATP is produced in anaerobic respiration?
2 ATP molecules
In anaerobic conditions, pyruvate converts to lactate through anaerobic glycolysis. Anaerobic respiration results in the production of 2 ATP molecules.
Why anaerobic respiration produces less ATP than aerobic respiration?
Anaerobic respiration occurs only in the cytoplasm of cells. Glucose is not completely broken down, so much less ATP is released than during aerobic respiration. The lactic acid that builds up needs to be oxidised to carbon dioxide and water.
How is ATP produced in respiration?
Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. The energy of O2 released is used to create a chemiosmotic potential by pumping protons across a membrane. This potential is then used to drive ATP synthase and produce ATP from ADP and a phosphate group.
What produces ATP in cellular respiration?
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.
In which process is ATP produced?
The process human cells use to generate ATP is called cellular respiration. It results in the creation of 36 to 38 ATP per molecule of glucose. It consists of a series of stages, beginning in the cell cytoplasm and moving to the mitochondria, the “power plants” of eukaryotic cells.
Where do most reactions of respiration occur?
While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.
How many ATP are produced in TCA cycle?
2 ATPs are produced in the TCA cycle per glucose molecule (2 acetyl CoA). ATP is produced when Succinyl CoA produces succinate by the enzyme succinyl CoA synthetase.
Why does cellular respiration produce more ATP than fermentation?
Cellular respiration, like burning, results in the complete oxidation of glucose into CO2 and water. Fermentation, on the other hand, does not fully oxidize glucose. Instead, small, reduced organic molecules are produced as waste. As a result, cellular respiration releases more energy from glucose than fermentation.
What is the main product of cellular respiration?
Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Where and how does respiration take place?
Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell’s cytoplasm. The energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move.
