how many molecules of atp are produced in aerobic versus anaerobic cellular respiration?
212346
Anaerobic respiration makes a total of 2 ATP. Aerobic respiration is much more efficient and can produce up to 38 ATP with a single molecule of glucose.
1263404
Simplified reaction: 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.

ATP Yield. In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain.
9587
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).
469776
A molecule of glucose can only produce three ATP molecules under anaerobic metabolism, while it produces 39 with aerobic metabolism. ATP is what fuels the muscles. Anaerobic metabolism can only use glucose and glycogen, while aerobic metabolism can also break down fats and protein.

While aerobic respiration and fermentation both produce energy, the products of the processes are in different forms. The products of aerobic respiration are carbon dioxide, water, and energy in the form of ATP. The products of lactic acid fermentation are lactic acid and NAD+.
328123
This produces 2 ATP and 6 NADH , for every glucose molecule entering glycolysis. The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle).
398636
Similarities. Both aerobic and anaerobic respirations are types of cellular respiration. It is clear both use glycolysis to produce ATP. Both generate energy by breaking down glucose, produce byproducts and depend on chemical reactions that are localized in the cytosol.
536888
Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. ... Anaerobic respiration also produces energy and uses glucose, but it produces less energy and does not require oxygen.
1230565
Aerobic respiration is the process of conversion of energy into ATP in the presence of oxygen, while anaerobic respiration is the process of respiration in the absence of oxygen. Fermentation is the process of conversion of sugars to acids, alcohols or gases in the absence of oxygen.
966360
During aerobic respiration, carbon dioxide, water, and ATP are produced. During anaerobic respiration, lactic acid, ethanol, and ATP are created. ... It's important to note, however, that animals do go through lactic acid fermentation, which is anaerobic. This happens when muscle cells cannot get enough oxygen.
869293
Definition. Aerobic respiration is the process by which organisms use oxygen to turn fuel, such as fats and sugars, into chemical energy. ... The product of respiration is a molecule called adenosine triphosphate (ATP), which uses the energy stored in its phosphate bonds to power chemical reactions.

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.
247805
In addition to ATP, the Krebs cycle produces high-energy FADH2 and NADH molecules, which provide electrons to the oxidative phosphorylation process that generates more high-energy ATP molecules. For each molecule of glucose that is processed in glycolysis, a net of 36 ATPs can be created by aerobic respiration.
1432740
Cellular respiration. Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). 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.
1066741
With oxygen, organisms can use aerobic cellular respiration to produce up to 36 molecules of ATP from just one molecule of glucose. Without oxygen, organisms must use anaerobic respiration to produce ATP, and this process produces only two molecules of ATP per molecule of glucose.
705308
Aerobic respiration and fermentation are two processes which are used to provide energy to cells. In aerobic respiration, carbon dioxide, water, and energy in the form of adenosine triphosphate (ATP) is produced in the presence of oxygen. Fermentation is the process of energy production in the absence of oxygen.
