how many atp molecules are produced from one glucose?

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).
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.

Importantly, by the end of this process, one glucose molecule generates two pyruvate molecules, two high-energy ATP molecules, and two electron-carrying NADH molecules.

Glycolysis produces 2 ATP molecules, and the Krebs cycle produces 2 more. Electron transport begins with several molecules of NADH and FADH2 from the Krebs cycle and transfers their energy into as many as 34 more ATP molecules.
717248
The electron transport chain can convert the energy from one glucose molecule's worth of FADH2 and NADH + H+ into as many as 34 ATP. ... If oxygen is available, cellular respiration transfers the energy from one molecule of glucose to 38 molecules of ATP, releasing carbon dioxide and water as waste.

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.

Glycolysis starts with one molecule of glucose and ends with two pyruvate (pyruvic acid) molecules, a total of four ATP molecules, and two molecules of NADH.
756536
Most of the ATP produced during cellular respiration is made during this stage. For each glucose that starts cellular respiration, in the presence of oxygen (aerobic conditions), 36-38 ATP are generated. Without oxygen, under anaerobic conditions, much less (only two!) ATP are produced.

1 Answer. Well in one mole of glucose there are 6.022×1023 individual glucose molecules.

5 moles of glucose produces 20 moles of ATP and consumes 10 moles of ATP.
28990
In the mitochondria, the metabolism of sugars is completed, and the energy released is harnessed so efficiently that about 30 molecules of ATP are produced for each molecule of glucose oxidized.
1281436
Cellular respiration takes place in the cells of animals, plants, and fungi, and also in algae and other protists. In aerobic respiration, one molecule of glucose yields 38 ATP molecules, eight produced during glycolysis, six from the link reaction and 24 from the Krebs cycle.

This is where glucose is oxidized to form two pyruvate molecules. This yields 2 ATP (4 is actually produced but 2 is consumed in the initial steps) and 2 NADH ( will be crucial later to create more ATP). Henceforth, the total energy yield of the oxidation of glucose to carbon dioxide and water is 32 ATP Molecules.

6. 2 molecules of ATP are produced as a result of the Krebs cycle.
559542
The electron transport chain produces 28 ATP molecules. Since 4 ATP molecules were produced earlier in the cellular respiration process, this means...

Combining the contributions from glycolysis (Equation 5.12) and the TCA cycle (Equation 5.11) under aerobic conditions yields 38 ATP for the complete oxidation of one molecule of glucose to CO2 and H2O (Equation 5.13).

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.
