Hai everyone, im new to this forum and i am really confuse and curious about this. In cellular respiration, there are three process, glycolysis, kerbs cycle and electron transport chain. Kerbs cycle and electron transport chain cant proceed without the presence of oxygen. So the only possibilities on how the energy is produced during anaerobic respiration is through glycolysis. The output of glycolysis is 2 pyruvic acid, 2NADH, 2H20 and 2ATP. The thing that doubt me is that pyruvic acid must undergo fermentation to form lactic acid. But the thing is one of the output of glycolysis is NADH not NADH2. Whereas the equation shows that 2C3H4O3 + NADH2 --> 2C3H6O3 + NAD + 2ATP.
Im sorry, this may sounds a bit complicated but i really need guidance.
I know that this is a very broad and complicated topic.
Please correct me if im wrong.
Thanks
