Need help with sequences in celluar respiration

Anaerobic Respiration:
2 pyruvic acid ==> 2 ____________
OR
2 pyruvic acid ==> 2 ____________ + 2 ______________


Aerobic Respiration:
2 pyruvic acid + oxygen ==> __________+ ____________ + __________ ATP

Please help; I can't find the answer anywhere >_>
Thanks!

I'm really not sure, but I'm going to try...I really didn't understand the celluar respiration chapter.
Anaerobic Respiration:
2 pyruvic acid ==> 2 CO2 (alcohol fermentation)
OR
2 pyruvic acid===> 2 NAD+ + 2 NADH + H+ (lactic acid fermentation)


Aerobic Respiration:
2 pyruvic acid + oxygen ==> 6CO2+ 6H2O + energy(ATP+heat)
(Citric Acid Cycle and electron transport chain)
