Fermentation Honors

What is fermentation?

• Fermentation is a process that converts vitamins to acids, gases, or alcohol.

• Fermentation is a metabolic process that converts sugar to acids, gases, or alcohol.

• Fermentation is a process that converts fats to acids, gases, or alcohol.

• Fermentation is a process that converts proteins to acids, gases, or alcohol.

Name two types of fermentation.

• Alcoholic fermentation and lactic acid fermentation

• Aerobic fermentation and anaerobic fermentation

• Yogurt fermentation and sourdough fermentation

• Butyric acid fermentation and propionic acid fermentation

What are the main products of alcoholic fermentation?

• Ethanol and carbon dioxide

• Glucose and fructose

• Acetic acid and water

• Methanol and oxygen

Which microorganism is responsible for alcoholic fermentation?

• Yeast

• Bacteria

• Virus

• Mold

What is the role of yeast in fermentation?

• Yeast converts alcohol into sugar in fermentation.

• Yeast has no role in fermentation.

• Yeast converts sugar into alcohol and carbon dioxide in fermentation.

• Yeast produces sugar in fermentation.

What is the difference between aerobic and anaerobic fermentation?

• Aerobic fermentation produces more ATP than anaerobic fermentation.

• Aerobic fermentation requires oxygen, while anaerobic fermentation does not require oxygen.

• Aerobic fermentation produces lactic acid, while anaerobic fermentation produces ethanol.

• Aerobic fermentation occurs in the presence of oxygen, while anaerobic fermentation occurs in the absence of oxygen.

What is the purpose of lactic acid fermentation?

• The purpose of lactic acid fermentation is to produce carbon dioxide as a waste product.

• The purpose of lactic acid fermentation is to generate ethanol as a byproduct.

• The purpose of lactic acid fermentation is to regenerate NAD+ molecules and continue ATP production in the absence of oxygen.

• The purpose of lactic acid fermentation is to produce oxygen for cellular respiration.

What are the main products of lactic acid fermentation?

• glucose and water

• lactic acid and carbon dioxide

• ethanol and carbon dioxide

• lactic acid and oxygen

Which microorganisms are involved in lactic acid fermentation?

• Lactobacillus, Streptococcus, and Bifidobacterium

• Staphylococcus, Pseudomonas, and Bacillus

• Escherichia coli, Salmonella, and Shigella

• Aspergillus, Penicillium, and Rhizopus

How is fermentation used in the production of food and beverages?

• Fermentation is used to increase the sugar content in food and beverages.

• Fermentation is used to convert sugars and carbohydrates into alcohol, organic acids, and gases in the production of food and beverages.

• Fermentation is used to preserve food and beverages by adding chemicals.

• Fermentation is used to create artificial flavors in food and beverages.
