Can occur in absence of oxygen.
Oxygen must be present.
Oxygen is final electron acceptor.
Glucose is used.
Energy is released in the absence of oxygen.
Energy is released in the presence of oxygen.
May produce alcohol.
Occurs in mitochondria.
ATP is used as energy carrier.
Pyruvic acid is formed.
Occurs as a series of reactions rather than
as a single reaction.
Phosphates are involved in the reaction.
Enzymes are involved in the reaction.
Synthesis of ATP is involved in the reaction.
Carbon dioxide is produced.
Energy is released.

NAD contains “high energy” phosphate bonds.
Lactic acid builds up in overworked muscle because of a lack of oxygen.
ATP is produced during both aerobic and anaerobic respiration.
No enzymes are necessary in glycolysis and citric acid cycle.

3.
Anaerobic organisms, which can survive on fermentation, are very small and almost always
unicellular. Aerobic organisms, however, can be as large and complex as whaled and redwood
trees. How might these differences between anaerobic and aerobic organisms be explained by
their means of obtaining energy?
