After Harry was accepted to Hogwarts in 1991, Hagrid was given the task of actually locating Harry, as Harry's uncle Vernon was doing everything in his power to prevent his nephew from receiving his Hogwarts acceptance letter.
Sucrose is a disaccharide that yeast cells convert to glucose for alcoholic fermentation. When the yeast cells produce CO 2, this gas is trapped in bubbles in a layer of foam. Your teacher will pass around a cup with a foam layer so you will know what it looks like.
Alcohol fermentation is pretty similar to lactic acid fermentation. Instead of the pyruvate being reduced to lactate, it is reduced to ethanol, and lets off two molecules of CO 2 along the way. Two kinds of organisms use alcohol fermentation: bacteria and yeast (yeast are fungi, btw).Humans use alcohol fermentation in another way, by using it to make bread, beer and wine. We'll talk more about that in another section.lcohol fermentation is pretty similar to lactic acid fermentation.
