Alcohol fermentation is used to produce the carbonation (gas bubbles) in beer by combining yeast with maltose. Explain how that is possible in the context of the experimental results above

yeast is used to break down maltose into glucose molecuse, in absence of oxygen

In fermentation, state by yeast, the deficient oxidation of glucose is accomplished under anaerobic conditions by sets of reactions where pyruvic corrosive is changed over to CO₂ and ethanol. The enzymes, pyruvic corrosive decarboxylase and liquor dehydrogenase catalyze these reactions.
