1.
What are the products of aerobic respiration?
Lactic acid only
Carbon dioxide and water
Ethanol and carbon dioxide
Glucose and oxygen
2.
Anaerobic respiration in yeast produces:
Lactic acid
Oxygen
Water only
Ethanol and carbon dioxide
3.
Where does most aerobic respiration take place?
Mitochondria
Nucleus
Ribosomes
Chloroplasts
4.
Why does anaerobic respiration release less energy than aerobic?
It uses more oxygen
It happens faster
Glucose is only partially broken down
It only occurs in plants
5.
Which balanced equation is correct for aerobic respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O
C6H12O6 → 2C2H5OH + 2CO2
6CO2 + 6H2O → C6H12O6 + 6O2
C6H12O6 + 3O2 → 3CO2 + 3H2O
6.
Which statement best describes Oxygen debt?
Organelles in which most reactions of aerobic respiration take place.
Anaerobic respiration in yeast, producing ethanol and carbon dioxide.
The extra oxygen needed after exercise to break down lactic acid.
Respiration using oxygen, releasing a large amount of energy and producing carbon dioxide and water.
7.
Which statement best describes Anaerobic respiration?
Respiration using oxygen, releasing a large amount of energy and producing carbon dioxide and water.
Apparatus used to measure the rate of respiration by oxygen uptake.
Organelles in which most reactions of aerobic respiration take place.
Respiration without oxygen, releasing much less energy per glucose molecule.
