Answer: Option (C) is the correct answer.
Explanation:
In a cell, when glucose breaks down by the use of oxygen and yields carbon dioxide, water along with release of energy is known as aerobic respiration.
For example, in the mitochondria aerobic respiration takes place.
On the other hand, in a cell when glucose breaks down without the use of oxygen then it yields alcohol, carbon dioxide along with release of energy is known as anaerobic respiration.
For example, yeasts respire anaerobically.
Therefore, we can conclude that the main difference between aerobic respiration and anaerobic respiration is that aerobic respiration requires oxygen, and anaerobic respiration does not.
