Aerobic and Anaerobic Respiration Flashcards
What is aerobic respiration?
Respiration using oxygen.
Aerobic respiration is the most efficient way to_?
Transfer energy from glucose.
When does Aerobic respiration happen in plants and animals?
All the time.
Where do most of the reactions in aerobic respiration happen?
Inside mitochondria.
What is the word equation for aerobic respiration?
glucose + oxygen -> carbon dioxide + water
What is the symbol equation for aerobic respiration?
C6 H12 06 + 602 -> 6C02 + 6H20
When is anaerobic respiration done?
When you do vigorous exercise and your body can’t supply enough oxygen to your muscles (as well as aerobic respiration).
What is anaerobic respiration?
Anaerobic means without oxygen. It’s the incomplete breakdown of glucose, making lactic acid.
What is the word equation for anaerobic respiration in muscle cells?
glucose -> lactic acid
What is the difference between anaerobic and aerobic respiration in terms of energy amount?
Anaerobic respiration does not transfer nearly as much energy as aerobic respiration. This is because glucose isn’t fully oxidised (because it doesn’t combine with oxygen).
When is anaerobic respiration useful?
Only in emergencies, e.g. during exercise when it allows you to keep on using your muscles for a while longer.
What can plants and yeast cells respire without?
Oxygen.
What do plants and yeast cells produce instead of lactic acid in anaerobic respiration?
Ethanol and carbon dioxide (instead of lactic acid).
What is the word equation for anaerobic respiration in plant and yeast cells?
glucose -> ethanol + carbon dioxide
What is anaerobic respiration in yeast cells called?
Fermentation.
