Which process is common to both aerobic and anaerobic organisms?

[FROGGBUSTER]

A. Krebs cycle
B. Fermentation
C. Glycolysis
D. Electron Transport Chain

Answer is pretty obvious, C.

But doesn't fermentation occur in both aerobic and anaerobic organisms as well?

If there was no oxygen, the aerobe would be functioning anaerobically therefore that answer is not found in both anaerobes and aerobes is my thinking.

Fermentation only occurs anaerobically, it does not occur in aerobic organisms. Meanwhile, glycolysis occurs in both.

Well facultative anaerobes can grow aerobically and anaerobically.....I think the question would have been better worded if they said "strict aerobes"

Fermentation occurs in BOTH. however humans have lactic acid fermentation aka when our muscles fatigue. plants and stuff and alcohol fermentation. but occurs mainly when oxygen is not present. because it only produces a very small amount of atp

 

[herkulease]

to me the question arises with choice electron transport chain.

both aerobic and anaerobic organisms have an ETC. the difference what the final electron acceptor is.

I put away my destroyer so I don't remember what he wrote in the back.

yeah this is what i thought.

where does the ETC occur in anaerobic organisms?

cytosol

come on buddy.... we'd never buy any boos if we can carry out fermentation 😀

unless it says Lactic Acid Fermentation, I believe it would mean general alcohol based fermentation, which occurs anaerobically. Plus Fermentation falls under Glycolysis, therefore it wouldnt make sense for the answer to be Fermentation.

my general biology professor actually stressed that fermentation includes both glycolysis + the oxidation of NADH part; it shouldn't be considered a part of glycolysis as you're implying, it's a separate process.

@spoog & herkulease: yea i looked it up, ETCs do exist in anaerobic organisms.


this is a terrible question lol. 👎

"Fermentation enables some cells to produce ATP without the use of oxygen"

"Both fermentation and cellular respiration use glycolysis to oxidize glucose and other organic fuels to pyruvate."

Thats taken right out of Campbell, I did not imply that glycolysis and fermentation are part of the same process. I just said the facts, that one RELIES on the other. There cannot be any fermentation without glycolysis, thus it wouldnt make sense to pick fermentation as the answer. As exam makers would say while fermentation might be technically correct, Glycolysis is the preferred answer or best answer.

i'm not trying to argue with you buddy.

Me neither, I'm just explaining why its a valid answer.
