This question asks, fermentation pathways make no more atp beyond the small yield from glycolysis.
00:09
The remaining reactions serve to regenerate blank.
00:13
And our answer choices are fad, nad plus, glucose, and oxygen.
00:20
So let's rule out oxygen right away.
00:23
And that is because if we are referring to fermentation, then we are referring to an anaerobic process, which means that it is completed in the absence of oxygen.
00:38
And specifically, if we are looking at fermentation, then we know that instead of oxygen, we will have either pyruvate or acetylaldehyde as our final electronic septors.
00:49
So without oxygen, we will not be producing this extra atp as a result of the electron transport chain or the krebs cycle...
