Anaerobic Respiration Flashcards
Which substance do muscles store glucose as?
Glycogen
What happens to the stored glucose in muscles during exercise?
Converts glycogen to glucose
Why do muscles carry out anaerobic respiration?
If too little oxygen is reaching them during exercise
How does the breakdown of glucose differ in aerobic and anaerobic respiration?
Anaerobic respiration is the incomplete breakdown of glucose
What is the product of anaerobic respiration?
Lactic acid
How does the amount of energy produced differ in aerobic and anaerobic respiration?
Less is produced in anaerobic
HT -How is the oxygen debt produced by anaerobic respiration repaid?
Lactic acid is oxidized (using oxygen) to carbon dioxide and water
Why do muscles become fatigued?
If they are subjected to long periods of vigorous activity
What does ‘ muscle fatigue’mean?
Muscles stop contracting efficiently
What is one of the causes of muscle fatigue?
The build-up of lactic acid
What is fermentation?
The anaerobic respiration in yeast it produces ethanol and carbon dioxide
