I am also confused, when I Google it i get 38, but that isn't an option on my homework assignment =/

I was told it was something to do with whether it was agreed that FADH produced any ATP.

It obviously does, but some exam boards refute this and so the answer is 36 ATP. I'm not entirely sure why...

A total of 38 ATP is produced but two is used up during the process so the net gain is 36. Of the 36, 2 comes directly from Glycolysis, and another 2 comes directly from the Krebs Cycles. The rest 32 comes from NADH and FADH2 that are produced by cellular respiration. These NADH and FADH2s dispose their hydrogen into the electon transport chain. The hydrogens drive the ATP synthase and each of them turns one ADP into ATP, resulting in another 32 ATPs.

This varies greatly. A textbook might say something like 36-38 molecules of ATP. This is under ideal conditions.

In the citric acid cycle ATP molecules are produced by?

Yes, 34-36 ATP are produced during the citric acid cycle with another two produced during glycolysis for a total of 36-38 ATP during cellular respiration.


What are the output of energy in cellular respiration?

During cellular respiration a molecule called Adenine triphosphate or ATP is produced which is used for many different aspects of a cell's functions. Another molecule that is produced that contains potential energy is called NADH. A net total of 2 ATP and 2 NADH is produced during the stages of cellular respiration known as glycolysis and linkage reactions.


How many ATP are produced in cellular respiration?

During the process of aerobic respiration as many as 38 molecules of ATP are produced for every molecule of glucose that is utilized. Thus aerobic respiration process breaks down a single glucose molecule to yield 38 units of the energy storing ATP molecules. However, it takes 2 ATP to start the process. A net 36 are produced.


How many atp are produced in cell respiration?

3/4 of the ATP is made in respiration To build on the original answer: 36 ATP are produced from glycolosis to Electron Chain Transport with oxygen being the final electron acceptor. Some sources cite that anywhere between 28 and 36 ATP are produced but if you plan on taking the MCAT if this question is asked the answer is 36.


Why is cellular respiration more efficient when oxygen is present in cells?

Without oxygen - only glycolysis occurs. This results in very few ATP molecules. With oxygen, all of celluar respiration occurs and this results in almost 40 ATP molecules. So, oxygen is essential to the production of mass ATP molecules.


How many atps are produced total in cellular respiration in eukaryotic cells?

36 in somatic cells and 38 in liver and heart cells.


How do you calculate the number of ATP molecules produced by aerobic respiration?

38 ATP molecules are produced in total (after 2 complete cycles)


What does 'anaerobic respiration is far less efficient than aerobic respiration' mean?

There are two types of cellular respiration: aerobic and anaerobic. Aerobic respiration occurs when there is oxygen present. In total, 36 ATP are produced by the end of aerobic respiration. Anaerobic respiration occurs when there is no oxygen present. In total, just 4 ATP are produced by the end of anaerobic respiration. Thus, aerobic respiration is more efficient in comparison to anaerobic respiration as it yields more ATP
