List the similarities and difference between aerobic and anaerobic respiration
Similarities between Aerobic and Anaerobic Respiration
Both release energy from glucose (or food molecules).
Both start with glycolysis in the cytoplasm.
Both involve enzymes for breaking down glucose.
Both produce by-products (though different in type).
Differences between Aerobic and Anaerobic Respiration
Feature |
Aerobic Respiration |
Anaerobic Respiration |
---|---|---|
Oxygen requirement |
Occurs in presence of oxygen |
Occurs in absence of oxygen |
Site in cell |

Only in cytoplasm |
End products |
CO? + H?O + Energy (ATP) |
In animals: Lactic acid + Energy |
