How many ATP molecules does fermentation produce during cellular respiration?
Fermentation does not produce ATP molecules during cellular respiration. Instead, fermentation occurs in the absence of oxygen to regenerate NAD+ for glycolysis to continue. This process does not directly generate ATP.
Fermentation occurs when a cell does not get enough what?
Fermentation occurs when a cell does not get enough oxygen to carry out aerobic respiration. Instead, the cell uses anaerobic pathways to produce energy in the form of ATP.
The breakdown of glucose for energy is called?
Fermentation
What is involved in the anaerobic phase in fermenting beer?
There are two stages to the kind of anaerobic cellular respiration you are talking about: One (Glycolysis): Glucose is broken down via a process called Glycolysis into Pyruvate. Glycolysis does not require oxygen, therefore it can occur in Aerobic (Oxygen rich) or Anaerobic (Oxygen defficient) settings. Two (Ethanol Fermentation): 1. Pyruvate is converted into Acetylaldehyde and CO2. 2. NADH reduces Acetylaldehyde (gives it a proton/ H molecule) which converts it into ethanol (alhohol.) (Both of these phases can be considered Anaerobic, as no Oxygen is used. Glycolysis occurs in any condition (Aerobic/Anaerobic) but Fermentation occurs only in Anaerobic conditions. Ethanol Fermentation occurs only in Anaerobic conditions and in organisms such as yeast and some bacteria. In animal cells, when not enoguh O2 is present, lactic acid is created as a by-product instead of ethanol. (Remember that episode of The Magic School bus when they were inside someone and there was that white goo on their muscles? That was lactic acid.) The purpuse of cellular respiration is to convert sugars into energy that the body can use (ATP, NADH and FADH2.) It is not very efficitnt, and creates much less energy than Aerobic Cellular Respiration would (which performs Glycolysis and then breaks the resulting pyruvate down into CO2 and H2O.)
What organ does respiration occur in?
Virtually all oxygen using organisms have cellular respiration going on. C.R. is the breakdown of glucose using oxygen to release energy as ATP - so anything - plants, animals, single celled organisms - that take in oxygen and glucose are going to do CR. Organisms that can't tolerate oxygen or run out of oxygen (like your muscles during a strenuous workout) will do fermentation instead. Fermentation will get the job done but respiration releases much more energy per molecule of glucose.
Under what conditions does a use fermentation instead of cellular respiration?
low oxygen
Under what condition does a cell Use fermentation instead of cellular respiration?
low oxygen
Does anaerobic cellular fermentation use the same final electron acceptors as aerobic respiration?
No, because the electron acceptor is what cates the electrons as the leave the electron transport chain, which is oxygen in aerobic respiration. Since aerobic respiration uses oxygen, and anaerobic fermentation is abest of oxygen, anaerobic fermentation cannot possibly use oxygen as respiration does.
How many ATP molecules does fermentation produce during cellular respiration?
Fermentation does not produce ATP molecules during cellular respiration. Instead, fermentation occurs in the absence of oxygen to regenerate NAD+ for glycolysis to continue. This process does not directly generate ATP.
Explain why muscles must use lactic acid fermentation instead of cellular respiration during intense physical activity?
Because mammalian muscle cells are genetically programmed to perform lactic acid fermentation, not ethanol fermentation.
How might an organism benefit by carrying Out fermentation instead of cellular respiration?
Organisms prefer cellular respiration over fermentation.Cellular respiration gains a cell 38ATP molecules per every glucose molecule.Fermentation only gains 2ATP per glucose molecule.Obviously, you can see the difference. Cellular respiration provides much more energy for the cell, and this is why they prefer this over fermentation.There are organisms like facultative anaerobes that can preform either process, but they do cellular respiration if oxygen is available. These organisms only preform fermentation if they are in an "oxygen debt." (Like when you run, you are using a lot of energy, and you cannot get enough oxygen for cellular respiration. You are in "oxygen debt," and your muscle cells start doing fermentation. But your muscle cells prefer using aerobic reparation (cellular respiration) so you start panting. Once you get your breath back, oxygen is restored and your cells again preform cellular respiration and get more energy faster.)However, there are still obligate anaerobes that are poisoned by oxygen, and only use fermentation.Hope this helped!!
Why would your body go through lactic acid fermentation instead of cellular respiration?
Lactic acid will be the temporary end point of cellular respiration while oxygen supplies are limited, as while enduring exertion. This temporary presense of an excess amount of acid in the muscle tissue is what causes the feeling 'muscle burn'.
Why would an organism use fermentation instead of respiration?
a lack of oxygen
What type of cellular respiration occurs with oxygen?
Aerobic respiration is the type of cellular respiration that requires oxygen. This process involves the release of glucose for energy.Aerobic respiration requires oxygen to be present because it is the final electron acceptor at the end of the electron transport chain. If it is not present, then the electron can not go through the chain and fermentation will cycle instead. Fermentation is much more inefficient in producing ATP (a differenence of 32 ATP).
How does human cells use fermentation?
Fermentation is simply anaerobic cellular respiration where an organic compound is used as an electron acceptor instead of using oxygen. Consequently, lots of types of cells can utilize fermentation. There are examples of both prokaryotes and eukaryotes that are capable of anaerobic respiration. The most common example of fermentation is in the yeast cell, which produces the alcohol found in beer. Another example is the human muscle cell, which produces lactic acid through fermentation when there is not enough oxygen present to continue cellular respiration (such as after a long jog).
Cellular respiration does not produce what?
GlucoseIt mainly produce ATPs. Water and CO2 are bi products
What kind of organisms use cellular restpiration?
All of them do except for ones that instead use fermentation
