1
Q
What does increase ?
A
Aerobic Respiration
2
Q
Body cells need more what and why?
A
More OXYGEN for aerobic respiration to release energy.
3
Q
What happens when not enough OX. is supplied to muscles?
A
Anaerobic respiration takes place.
Which produces lactic acid.
4
Q
Why lactic acid is released during anaerobic respiration?
A
Because the oxidation of glucose is INCOMPLETE.
5
Q
What does lactic acid do?
A
Causes muscles to become tired.
And muscles stop contracting efficiently.
6
Q
What is oxygen debt?
A
Muscles need to remove lactic acid through blood. Oxygen is needed to carry this process. Therefore, oxygen is both needed to deal with accumulated lactic acid and anaerobic respiration.
