Respiration and Fermentation Quiz

What is the main difference between aerobic and anaerobic respiration?

• Aerobic respiration does not require oxygen.

• Anaerobic respiration occurs in the presence of oxygen.

• Aerobic respiration uses an electron transport chain.

• Anaerobic respiration produces more ATP.

Which phase of aerobic respiration generates the most ATP?

• Krebs Cycle

• Glycolysis

• Electron Transport Chain

• Fermentation

What is the role of NAD+ in glycolysis?

• It acts as a final electron acceptor.

• It generates ATP directly.

• It carries electrons to the electron transport chain.

• It breaks down glucose into pyruvate.

What is the net gain of ATP molecules during glycolysis?

• 8 ATP

• 6 ATP

• 4 ATP

• 2 ATP

Which molecule is the final electron acceptor in lactic acid fermentation?

• Oxygen

• Nitrate

• Pyruvate

• Acetaldehyde

What is a byproduct of alcoholic fermentation?

• Lactic acid

• Oxygen

• Water

• Carbon dioxide

Which process is used by yeast to produce alcohol?

• Aerobic respiration

• Anaerobic respiration

• Lactic acid fermentation

What is the main difference between fermentation and anaerobic respiration?

• Fermentation uses an electron transport chain.

• Anaerobic respiration does not involve glycolysis.

• Fermentation does not use an electron transport chain.

• Anaerobic respiration occurs only in yeast.

Which of the following is not a final electron acceptor in anaerobic respiration?
