Multiple choice

The number of ATP molecules produced during aerobic and anaerobic respiration are _______ and ______ respectively.

  1. 2 and 34

  2. 2 and 30

  3. 0 and 2

  4. 38 and 2

D Correct answer
Explanation

The theoretical maximum ATP yield from aerobic respiration is 38 ATP (or sometimes cited as 36). Anaerobic respiration (fermentation) produces only 2 ATP per glucose molecule - the net gain from glycolysis alone since fermentation doesn't produce additional ATP. Options A and B have the order reversed, while option C is incorrect as glycolysis does produce 2 ATP even in anaerobic conditions.
