Energy from Respiration: Anaerobic Respiration Flashcards
1
Q
What happens when the muscles have insufficient amounts of energy?
A
they use anaerobic respiration
2
Q
What is anaerobic respiration?
A
incomplete breakdown of glucose and production of lactic acid
3
Q
What type of respiration is more efficient?
A
- aerobic: more efficient
- anaerobic doesnt produce as much energy because of the incomplete breakdown of glucose
4
Q
What does the build up of lactic acid cause?
A
muscle fatigue
5
Q
How is lactic acid removed?
A
blood flow through muscles
6
Q
How is lactic acid broken down?
A
using oxygen to produce carbon dioxidde and water
7
Q
What is the term for the extra oxygen needed to breakdown lactic acid?
A
oxygen debt
8
Q
What helps to break down the lactic acid?
A
warming down
9
Q
How is heart and breathing rate affected by oxygen debt?
A
- stay high in order to pay off debt
fitter you are, easier to pay off debt
