How many times greater is the How many times greater is the ATP production by respiration than by fermentation?

A.T.P. production by respiration is greater than fermentation because most of the energy remains locked up in the products of fermentation (alcohol of lactic acid) formed from pyruvic acid.

Where in your body can you use anaerobic respiration?
In your muscle cells. In your case, the only fermentation your cells are going through is lactic acid fermentation (and not alcohol fermentation). Anaerobic respiration occurs in the absence of oxygen. If there is oxygen present, then your cells will go through aerobic respiration normally. However, there are times when your cells lack oxygen, as in intense exercise. When cells can do both aerobic and anaerobic respiration, it is called facultative respiration.
Why do we do cellular respiration?
Cellular respiration is the process by which cells produce ATP for energy. Also, cellular respiration is much more efficient than fermentation, the process by which single celled organisms. (Cellular respiration produces 18 times more ATP than fermentation) Essentially, without cellular respiration is what keeps the cells in your body functioning.
What does cellular respiration occurs in the presence of?
Generally it will occur in the presence of oxygen, which is aerobic respiration, but there are other times where no oxygen will be present and cellular respiration will occur anaerobically (fermentation). Aerobic respiration is more beneficial because you produce more ATP than anaerobically.
What is the different respiration and fermentaion both break down sugar to produce energy?
respiration is in presence of oxygen which leads to complete breakdown of sugar yielding many times more energy than in fermentation which is in absence of oxygen
What happens to muscles when there is not enough oxygen?
oxygen debt. more oxygen is needed than what is being supplied. the body then begins anaerobic respiration (the cells "breathe" for you). a result of anaerobic respiration is lactic acid. lactic acid is that soreness feeling you get after a hard workout
When there is not enough oxygen for aerobic respiration what is that called?
During times of insufficient oxygen, the cell undergoes glycolysis, where 2 existing molecules of ATP can form 4 molecules and pyruvic acid. This is an insignificant amount compared to 38 molecules of ATP made by the cellular respiration, which is why it is important to always have enough oxygen.
Differentiate aerobic and anaerobic respiration?
Hi, For this answer, i am assuming you have some high school biology knowledge (general understanding of glycolysis, kreb cycle, pyruvate oxidation etc..) Anaerobic respriation and fermentation differ in the chemical pathways. Fermentation occurs when the pyruvate (or some derivative of it) that is produced after glycolysis is reduced by NADH to usually form an organic compound (lactic acid in lactic acid fermentation and ethanol in alcoholic fermentation). It is important to note that fermentation does not have to occur in anaerobic evironments, for example yeast prefers fermentation even in the presence of oxygen (as long as sugars are available). Therefore, the defining characteristic of fermentation is that the electrons from the coenzymes (NADH from the glycolosis) are transfered back to part of the original substrate (pyruvate). Note that the electrons are donated to something which came from within the cell (pyruvate). On the other hand, anaerobic respiration is actually very similar to aerobic respiration. In anaerobic respiration, you would go through glycolysis, pyruvate oxidation, kreb cycle and then electron transfer chain just as you would in aerobic respiration with the difference that that the terminal electron acceptor is NOT oxgyen (nitrate, nitrite etc..). The defining characteristic here is that the terminal electron acceptor is anything by oxygen but otherwise, it is very similar to aerobic respiration. Note that the electrons are donated to something which came from outside the cell (nitrate, nitrite etc..). Therefore, fermentation goes something like glycolysis -> donating electron back to pyruvate or a derivative of pyruvate (electron acceptor from internal source); while anaerobic respiration goes something like glycolysis -> pyruvate oxidation -> kreb cycle -> electron transfer chain with terminal electron acceptor being anything but oxygen (electron acceptor from external source). Hope this made sense
