Question 3: Fill in the blank: The equation for aerobic respiration is glucose + oxygen -> carbon dioxide + water + _____.

Answer: energy

Question 4: True or False: Anaerobic respiration produces more energy than aerobic respiration.

Answer: False

Question 5: True or False: During intense exercise, muscles may switch to anaerobic respiration.

Answer: True

Question 6: Explain the role of mitochondria in respiration.

Answer: Mitochondria are the site where respiration occurs, releasing energy.

Question 7: What is the chemical equation for aerobic respiration?

Answer: C6H12O6 + 6O2 -> 6CO2 + 6H2O + energy

Question 8: Why do muscle cells perform anaerobic respiration during high-intensity exercise?

Answer: Because oxygen supply is insufficient for aerobic respiration.

Question 9: Calculate the total ATP yield from one molecule of glucose through aerobic respiration. Use the formula: 1 glucose = 36 ATP

Answer: 36 ATP

Question 10: Order the following steps of aerobic respiration:

Question 11: Discuss the differences between aerobic and anaerobic respiration in terms of energy yield and by-products.

Answer: Aerobic respiration yields more energy (36 ATP) compared to anaerobic (2 ATP). By-products for aerobic are CO2 and water, while anaerobic produces lactic acid or ethanol.
