Fermentation releases less energy than respiration because it does not completely oxidize glucose. Fermentation does not utilize the Kreb Cycle or the electron transport system, leaving it with a gain of just 2 ATP from substrate level phosphorylation.

Fermentation does not use oxygen and produces ethanol compared to aerobic which gives energy, water and carbon dioxide so it must it must have something to do with the oxygen since it is the only factor that changes

In fermentation, the distance between the pyruvate and the final electron acceptor is shorter and therefore not as much energy is produced.

Because fermentation does not involve the Krebs's cycle and the electron transport system. This is because of lack of oxygen.

How does the amount of energy resulting from fermentation compare with that of aerobic respiration?

2 net ATP/36 net ATP * 100 = 5.6% ============Fermentation only yields about 5.6% as much energy as aerobic respiration.


Compare aerobic respiration and fermentation in terms of efficiency of obtaining energy from glucose?

ATP or adenosine triphosphate provides the energy for the cells. Aerobic respiration is more efficient because it produces 32 ATP, while fermentation only produces 2 ATP.


Aerobic respiration anaerobic respiration and fermentation are?

Anaerobic respiration is not the same as fermentation, although it does happen in the absence of oxygen unlike aerobic respiration which is when glucose and oxygen react to create carbon dioxide, water and energy. Basically, aerobic respiration is what animals do to gain energy and it is the opposite of photosynthesis.


How is fermentation diffrent than aerobic respiration?

Produces far less energy than aerobic respiration. That's the main difference.


Which releases more energy aerobic or cellular?

That's not a full question, but I think I know what you are asking. Aerobic respiration > anaerobic respiration > fermentation.


Aerobic Chemoorganotrophs?

Obligate aerobes obtain energy using aerobic respiration exclusively -> None use fermentation


Is it false that the energy yield in aerobic respiration is far less than that which results from fermentation?

Fermentation gives you 2 net ATP per glucose... aerobic respiration gives you 36-38 net ATP per glucose... so aerobic gives you more energy than fermentation.


Differences between fermentation and respiration?

one uses oxygen to get energy and the other uses yeast!Fermentation does not need oxygen. Aerobic respiration need oxygen


Do aerobic respiration anaerobic respiration and fermentation release energy?

Yes they release energy from glucose and store in ATP.Fermentation also anerobic process.


How does vibrio cholerae obtains its energy?

by aerobic respiration if oxygen is present, also capable of switching to fermentation


Does fermentation release more energy than respiration?

No, Respiration releases more energy than fermentation. i read it in my science book dont know why though


How are respiration and fermintation similar?

Respiration and fermentation are both instances of release of carbon dioxide by living organisms, in order to obtain energy after synthesizing food. Respiration occurs with the help of oxygen (aerobic) while fermentation is anaerobic.
