B9.3 Anaerobic respiration Flashcards
What is the equation of anaerobic respiration?
Glucose makes lactic acid + energy
Why does anaerobic respiration take place?
Because the blood cannot supply oxygen to the muscles fast enough
What is oxygen debt?
The build up of lactic acid in the muscles as a result of anaerobic respiration
What is one cause of muscle fatigue?
Build of lactic acid
Why do people pant and puff after you stop exercise?
The waste lactic acid you produce during anaerobic respiration gets converted into glucose in the liver - this process needs oxygen - therefore the body pants in order to get the oxygen
What is another way to define oxygen debt?
The amount of oxygen needed to convert the lactic acid to glucose
What is the equation for oxygen debt?
Lactic acid + oxygen makes carbon dioxide + water
What do plants produce when they respire anaerobically?
Ethanol + carbon dioxide
What is fermentation?
Where anaerobic respiration in yeast cells is known as fermentation
What is the equation for anaerobic respiration in plants?
Glucose makes ethanol + carbon dioxide + energy released to the environment
