Short answer that the teacher is looking for: You get cramps. You get lactic acid buildup. The previous answerer is right on... gotta love the Kreb's cycle!

absence of oxygen prevents pyruvate from being metabolised to CO2 and water via the citric acid cycle and the electron transport chain .
Various end products can also be created, such as lactate or ethanol.
Fermentation in animals is essential to human life.
In lactic acid fermentation, the following reaction occurs:
1. Glycolysis
C6H12O6 (glucose) + 2 NAD+ ---> 2 C3H4O3 (pyruvic acid) + 2 NADH
2. Lactic Acid Creation
2 C3H4O3 (pyruvic acid) + 2 NADH ---> 2 C3H6O3 (lactic acid) + 2 NAD+
In some plant cells and yeasts, fermentation produces CO2 and ethanol. The conversion of
pyruvate to acetaldehyde generates CO2
and the conversion of acetaldehyde to ethanol regenerates NAD+.

Pyruvate has to be changed into something else in order to keep it from building up and in order to free up the NAD to keep glycolysis going.
Lactic acid fermentation in muscle cells changes pyruvate into lactic acid.
Alcoholic fermentation in yeast cells changes pyruvate into ethyl alcohol and carbon dioxide.

cellular respiratory could be defined in could intensity if mandatory, yet usual cellular respiratory is breaking down the glucose molecule into usable potential (ATP) for the cellular. the 1st step in cellular respiratory is breaking down the glucose molecule by using glycolysis into pyruvic acid.right here there is two ATP that are produced. Then there is anaerobic respiratory ( if oxygen isn't modern-day) which incorporates alcohol fermentation/ lactic acid fermentation. If oxygen is modern-day then cardio respiratory occurs. the two important steps in cardio respiratory is Krebs Cycle ( 2 ATP produced) and Electron delivery Chain. ( as much as 36 ATP produced) i'm hoping this helps! =]

In the absence of oxygen, decarboxylation of pyruvate takes place; leading to the formation of ethanol.
