The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS).
What produces ATP in cellular respiration?
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 produces the greatest amount of ATP?
The metabolic cycle that provides the highest net ATP per glucose molecule is oxidative phosphorylation. In the mitochondria, aerobic respiration produces the greatest ATP per glucose module.
What pathway produces the most ATP?
Oxidative phosphorylation is the metabolic pathway that produces the most ATP.
What part of cellular respiration makes the most ATP Related Questions
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 produces the most ATP quizlet?
Which step in cellular respiration produces the most ATP? The electron transport chain.
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).
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).
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.
How much ATP is produced in each step of cellular respiration?
Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
How much ATP is produced in glycolysis and fermentation?
Fermentation Review Fermentation begins with glycolysis which breaks down glucose into two pyruvate molecules and produces two ATP (net) and two NADH. Fermentation allows glucose to be continuously broken down to make ATP due to the recycling of NADH to NAD+.
How much ATP is produced in each phase of cellular respiration?
One glucose molecule is metabolised to yield 38 ATP molecules during cellular respiration. The electron transport system produces 34 molecules of ATP out of a total of 38 molecules. During glycolysis, two ATP molecules are created inside the mitochondria and two ATP molecules are produced outside the mitochondria.
Which type of phosphorylation makes a lot of ATP?
Oxidative phosphorylation produces 24‚Äì28 ATP molecules from the Kreb’s cycle from one molecule of glucose converted into pyruvate.
How many ATP are produced by oxidative phosphorylation?
Electrons from NADH and FADH2 are then transferred to molecular oxygen, coupled to the formation of an additional 32 to 34 ATP molecules by oxidative phosphorylation.
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.
Which process produces the most ATP aerobic or anaerobic?
Aerobic respiration produces much more ATP than anaerobic respiration.
How much ATP does glucose produce in cellular respiration?
In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP.
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.
Is more ATP produced in fermentation?
Without oxygen, some human cells must use fermentation to produce ATP, and this process produces only two molecules of ATP per molecule of glucose. Although fermentation produces less ATP, it has the advantage of doing so very quickly.
How much ATP is produced in lactic acid fermentation?
During formation of lactic acid by anaerobic respiration 2 molecules of ATP are produced.
