In the absence of oxygen, what is the fate of the NADH produced in glycolysis?
Show answer and explanation
Correct answer: It donates electrons to pyruvate or acetaldehyde in fermentation.
In anaerobic conditions, NADH must be re-oxidized to NAD+ to allow glycolysis to continue. This is achieved by donating electrons to pyruvate (forming lactic acid) or acetaldehyde (forming ethanol).
