It is the process by which glucose is broken down to produce energy in the absence of oxygen. 2. It is the type of bacteria that produces lactic acid as its only by-product. 3. It is the product of decarboxylation of pyruvate. 31 Arrange the following events in alcoholic fermentation using letters A-E, with A being the first step and E being the last. 1. Alcohol dehydrogenase adds the hydride group from NADH to acetaldehyde. 2. The carboxyl group is removed from the pyruvate molecule. 3. A hydrogen ion is added to acetaldehyde. 4. Acetaldehyde is converted to ethanol 5. Pyruvate is converted to acetaldehyde. 32  Anaerobic fermentation is the process by which a glucose molecule is broken down to produce energy in the absence of oxygen. Fermentation is the process by which pyruvate is converted to either ethanol or lactate that enables the oxidation of NADH to NAD+. 33  The two fermentation processes are: ○Lactic acid fermentation is the process involving the conversion of pyruvate molecules to lactate through an enzyme called lactate dehydrogenase. 34  The two fermentation processes are: ○Alcoholic fermentation involves the conversion of pyruvate molecules into ethanol through the help of pyruvate decarboxylase and alcohol dehydrogenase. 35  The products of anaerobic respiration are 2 ATP, 2 NADH, and 2 pyruvate molecules. When pyruvate molecules undergo fermentation the products are either ethanol or lactate. Fermentation is widely used in the processing of dairy products and alcoholic 36 The two main types of anaerobic respiration 37
