In this video, we're going to briefly introduce alcohol fermentation. Alcohol fermentation is really similar to lactic acid fermentation, and the difference is that the pyruvate in alcohol fermentation is going to be reduced by NADH to form ethanol instead of forming lactic acid, and ethanol is really a type of alcohol. Now, alcohol fermentation is not only going to produce ethanol, but it's also going to regenerate the NAD+, allowing for glycolysis to continue even in the absence of oxygen.
Taking a look at our image down below, notice that we're showing you alcohol fermentation. Alcohol fermentation is basically going to be very similar to lactic acid fermentation. The only difference is that ethanol is going to be produced instead of lactic acid. Also, once again, the NAD+ is going to get regenerated through alcohol fermentation, and when NAD+ gets regenerated, that can be utilized to help continuously drive glycolysis even in the absence of oxygen, and glycolysis can continue to produce its very small amount of ATP.
Alcohol fermentation is really going to produce beer from barley, the beer that humans can drink, and also wine from grapes as well. Over here on the right-hand side, notice that we're just showing you an image of a brewery and ice-cold beer, just to remind you that alcohol fermentation is what can drive and produce the alcohols that we drink.
This here concludes our introduction to alcohol fermentation and we'll be able to get some practice as we move forward in our course. So I'll see you all in our next video.
