What is the purpose (to the cell) of each the following?
1/ glycolysis
2/ pyruvate oxidation
3/ Krebs cycle
4/ Electron transport chain
5/ fermentation pathways( after glycolysis)

Fermentation occurs in the absence of oxygen, but O2 is not found in any of the reactions of glycolysis or fermentation. So, what drives these reactions at the level of glycolysis and fermentation? A. In the formation of ethanol, acetaldehyde accepts electrons from NADH, regenerating NAD+ B. ATP is synthesized in glycolysis, only if NAD+ is regenerated during fermentation C. Pyruvate donates electrons to NADH in lactic acid fermentation D. NADH synthesized in glycolysis is used to oxidize pyruvate to acetyl CoA during fermentation reactions E. In the formation of ethanol, pyruvate is decarboxylated in a reversible reaction, once oxygen is present again
