what happens to the carbon atom during cellular respiration and fermentation?

Question

anonymous · Answer

It is oxidized (cellular respiration) 
It is reduced (lactate fermentation) 



CELLULAR RESPIRATION 
The simplified, OVERALL equation for cellular respiration is: 
C6H12O6 + 6O2 -> 6CO2 + 6O2 + energy (as ATP) 
Looking at that OVERALL equation, the carbon in glucose is oxidized to carbon dioxide. 


LACTATE FERMENTATION 
Fermentation occurs AFTER glycolysis, and works on the pyruvate produced by glycolysis. In lactate fermentation, pyruvate is reduced to lactate, 


I won't address the other possibilities.
