Anaerobic Respiration Flashcards
When is anaerobic respiration used?
During exercise, if insufficient oxygen is reaching the muscles
What is anaerobic respiration?
The incomplete breakdown of glucose, producing lactic acid
Why is much less energy produced from anaerobic respiration than from aerobic respiration?
As the breakdown of glucose is incomplete
What does anaerobic respiration result in?
An oxygen debt
An oxygen debt has to be repaid in order to oxidise the lactic acid into…
Carbon dioxide and water
What happens to muscles if they are subjected to long periods of vigorous activity?
They become fatigued
What does fatigued mean?
Muscles stop contracting efficiently
What’s one cause of muscle fatigue?
The build-up of lactic acid in the muscles
What removes the lactic acid?
Blood flowing through the muscles
