Biology (B2): Aerobic and anaerobic respiration

HideShow resource information
Why do we need to respire?
Energy that is then used to maintain body temperature, allow muscles to contract, cell growth, repair and maintenance.
1 of 10
The difference between oxygen taken in during exercise and oxygen needed is called what?
Oxygen defecit/ oxygen debt.
2 of 10
2 examples of when plants or micro-organisms would use anaerobic respiration.
Plants with roots in sodden soil and bacteria in puncture wounds.
3 of 10
What is the word equation for aerobic respiration?
Glucose + oxygen -> (energy released) + carbon dioxide + water
4 of 10
What is the chemical equation for aerobic respiration?
C6H12O6 + 6O2 -> 6CO2 + 6H2O + 2900KJ/mol of glucose.
5 of 10
What is the word equation for anaerobic respiration?
Glucose -> (energy released) + lactic acid
6 of 10
What is the chemical equation for anaerobic respiration?
C6H12O6 -> 2C3H6O3 + 120KJ/mol of glucose.
7 of 10
How is lactic acid removed form the muscles?
Via blood flowing through the muscles.
8 of 10
Due to anaerobic respiration not being able to gain enough energy, what happens to the body?
Heavy breathing -> Oxygen debt -> Not enough oxygen taken in during exercise
9 of 10
Why is anaerobic respiration not sustainable?
Lactic acid is poisonious -> causes muscle cramps & not enough energy produced.
