What does the term ' aerobic' mean?
Using oxygen
1 of 10
What is meant by 'anaerobic' respiration?
Respiration without using oxygen
2 of 10
What do muscle cells need more of during exercise?
Energy
3 of 10
What are the two waste products of aerobic respiration?
Carbon dioxide and water
4 of 10
which substances is stored in the muscles and can be converted into glucose?
Glycogen
5 of 10
What is the word equation for aerobic respiration?
glucose + oxygen -> carbon dioxide + water (+energy)
6 of 10
Why do muscles become fatigued (tired) during vigorous exercise?
Lactic acid builds up in the muscles
7 of 10
What changes occur to the breathing and heart rate during exercise?
The breathing and heart rate increases
8 of 10
Why do blood vessels in the muscles dilate during exercise?
It allows a frequent flow of blood to muscles which supplies oxygen and glucose to the muscles more quickly and removes carbon dioxide faster
9 of 10
Explain what is meant by an 'oxygen debt'.
The amount of oxygen needed to breakdown the lactic acid produced in anaerobic respiration
