Aerobic and Anerobic Respiration

What does aerobic respiration require that anaerobic respiration doesn't?

• Glucose

• Carbon dioxide

• Oxygen

• Lactic acid

What is a potential downside of anaerobic respiration?

• Requires a lot of oxygen

• Takes a long time to produce energy

• Produces lactic acid

• Produces a large amount of water

Which type of physical activity would primarily use aerobic respiration?

• 100m sprint

• Weightlifting

• Long-distance marathon

• High jump

Which of the following best describes the process of anaerobic respiration?

• glucose → oxygen + carbon dioxide

• glucose + oxygen → carbon dioxide + water

• glucose → lactic acid

• glucose + lactic acid → oxygen + water

During which activity would lactic acid likely build up in muscles?

• Reading a book

• Walking in the park

• Sprinting for 20 seconds

• Sleeping

What is the main end product of aerobic respiration besides energy?

• Glucose and oxygen

• Carbon dioxide and water

• Lactic acid and glucose

• Oxygen and lactic acid

If you're doing an activity and you start feeling a burning sensation in your muscles, which type of respiration are you likely using?

• Aerobic

• Anaerobic

• Both

• Neither

Why is aerobic respiration more suitable for longer durations of activity?

• It produces lactic acid quickly

• It requires no oxygen.

• It releases energy more slowly and steadily.

• It produces large amounts of glucose.

Which of the following activities is an example of anaerobic exercise?

• Swimming 20 laps in a pool

• Going for a 2-hour hike

• Lifting heavy weights for a few repetitions

• Riding a bicycle at a moderate pace for an hour

In the absence of sufficient oxygen in the muscles, what process takes over to provide energy?

• Digestion

• Photosynthesis

• Aerobic respiration

• Anaerobic respiration
