MICROANATOMY

Detailed explanation-1: -It produces carbon dioxide and lactic and acetic acids, which quickly lower the pH, thereby inhibiting development of undesirable microorganisms that might destroy crispness. The carbon dioxide produced replaces the air and facilitates the anaerobiosis required for the fermentation.

Detailed explanation-2: -When yeasts eat sugar and turn it into energy, they also produce carbon dioxide. This process is known as fermentation.

Detailed explanation-3: -Answer and Explanation: During alcohol fermentation, the fermentation pathway takes place in the cytosol of the yeast. In this process, pyruvate molecules (output of glucose via glycolysis) are broken down into both ethanol (ethyl alcohol) and carbon-di-oxide. Beer and wine are produced via alcoholic fermentation.
