Lactic Acid Fermentation Concepts

What does a molecule of glucose split into during glycolysis?

• Two pyruvate molecules

• Four ATP molecules

• Two NADH molecules

• Water and hydrogen ions

What is the main reason organisms perform lactic acid fermentation?

• To create a lot of ATP energy

• To make more NAD+ so glycolysis can continue

• To produce water for the cell

• To completely break down pyruvate

Which of the following foods is made using lactic acid fermentation?

• Bread

• Yogurt

• Beer

• Wine

Which of these is a product of lactic acid fermentation?

• Alcohol

• Carbon dioxide

• Lactic acid

• Oxygen

What is formed when pyruvic acid gains electrons during fermentation?

• Alcohol

• Carbon dioxide

• Lactic acid

• Water

What happens to NADH during lactic acid fermentation?

• It gains more electrons.

• It is oxidized to NAD+.

• It becomes pyruvate.

• It turns into a protein.

Which of these is a part of the NAD+ molecule?

• Glucose

• Amino acid

• Adenine

• Fatty acid
