Exercise and Respiration Quiz

What are the two types of respiration?

• Anaerobic and Fermentation

• Aerobic and Photosynthesis

• Photosynthesis and Fermentation

• Aerobic and Anaerobic

Why does the body need more energy during exercise?

• To decrease heart rate

• To relax the muscles

• To increase body temperature

• For muscle contraction

What happens to the breathing rate and volume during exercise?

• Breathing rate increases and volume decreases

• Breathing rate decreases and volume increases

• Both increase

• Both decrease

What is the main problem during intense exercise?

• The body temperature drops

• Too much oxygen is supplied to the muscles

• Not enough oxygen can be supplied to the muscles

• The heart rate decreases

What is produced in the muscles during anaerobic respiration?

• Oxygen

• Lactic acid

• Water

• Carbon dioxide

What causes muscles to become fatigued during long periods of vigorous activity?

• Lactic acid buildup

• Lack of water

• Excess oxygen

• Decreased heart rate

What is the oxygen debt?

• The amount of oxygen the body needs during sleep

• The amount of oxygen stored in the muscles

• The amount of extra oxygen the body needs after exercise

• The amount of oxygen needed before exercise

Where is lactic acid transported to be converted back to glucose?

• The lungs

• The heart

• The kidneys

• The liver

Why do people continue breathing rapidly after finishing exercise?

• To deal with the accumulated lactic acid

• To remove carbon dioxide

• To increase heart rate

• To cool down the body

What increases to pump oxygenated blood around the body during exercise?

• Muscle mass

• Body temperature

• Heart rate

• Breathing rate
