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.
This process makes energy available for cell activity in the form of a high-energy phosphate compound known as adenosine triphosphate (ATP). Alcoholic fermentation is identical to glycolysis except for the final step (Fig. 1). In alcoholic fermentation, pyruvic acid is broken down into ethanol and carbon dioxide. Lactic acid from glycolysis produces a feeling of tiredness; the products of alcoholic fermentation have been used in baking and brewing for centuries.
