Energy for life: Respiration Flashcards
What is the purpose of respiration?
The oxidisation of glucose to release energy in the form of ATP
How have we used anaerobic respiration of plants and fungi to help us? (Example Q)
Production of bread and beer
How have we used anaerobic respiration in bacteria to help us? (Example Q)
Production of yoghurt
What is the word equation for anaerobic respiration in plants and fungi?
Glucose –> Ethanol + Carbon Dioxide
What is the symbol equation for aerobic respiration?
C6H12O6 + 6O2 –> 6CO2 + 6H2O
What colour does hydrogencarbonate indicator turn with decreased carbon dioxide levels?
Purple
What colour does hydrogen carbonate indicator turn when bubbled through carbon dioxide?
Yellow
What colour does hydrogen carbonate indicator turn when bubbled through carbon dioxide?
Yellow
What is oxygen debt?
The extra oxygen needed to oxidise the lactic acid and break it down
What is the difference between anaerobic and aerobic respiration in animals?
Aerobic:
- Mitochondria.
- Releases a lot of ATP
- Complete oxidisation of glucose
Anaerobic:
- Cytoplasm
- Not a lot of ATP released
- Partial breakdown of Glucose due to lack of, or no oxygen.
What is the colour change of limewater when carbon dioxide is bubbled through it?
Clear to Cloudy
What colour does hydrogencarbonate indicator turn when exposed to atmospheric carbin dioxide levels?
Red
What is the word equation for aerobic respiration?
Glucose + Oxygen = Carbon dioxide + Water
Why is lactic acid a bad waste product in animals?
It is poisonous (in large quantities) and can cause cramps
What is the word equation for anaerobic respiration in animals and bacteria?
Glucose –> Lactic acid
