after the fermantation is done, how many ATPs are produced?? i know that 2 ATP is produced after the glycolysis and 2 ATP is produced after fermentation. So is total # of ATP produced is 4? or does 2ATP from glycolysis used up for fermanatation ????

Glycolysis is fermentation (ok their end products are different)...it's just semantics. Glycolysis refers to processes in living cells while fermentation refers to bacterial glycolysis. In either case it produces 4 ATP but since 2 are consumed in the processing the net is 2 ATP.

Fermentation is anaerobic respiration. It can occur in both eukaryotes and prokaryotes. As stated before, the 4 total ATP are produced during glycolysis. Fermentation doesn't consume ATP. NADH is converted to NAD+ in order to obtain lactate or ethanol ( depending on the organism) from pyruvate. This regenerates NAD+ so it can be used in glycolysis again to obtain the two net ATP.
