Question

Why is anaerobic respiration considered less efficient than aerobic respiration?

a
More oxygen is required for anaerobic respiration than for aerobic respiration.
b
Less energy is required during anaerobic respiration than aerobic respiration.
c
More ATP molecules are gained in aerobic respiration than in anaerobic respiration.
d
Less lactic acid is formed during anaerobic respiration than during aerobic respiration.

The correct answer is:

**c. More ATP molecules are gained in aerobic respiration than in anaerobic respiration.**

Anaerobic respiration produces less ATP than aerobic respiration because it does not fully oxidize glucose. While aerobic respiration can yield up to around 36-38 ATP molecules per glucose molecule, anaerobic respiration typically only produces about 2 ATP molecules per glucose molecule. This makes it less efficient in energy production compared to aerobic respiration.
