Final answer:
Cellular respiration is the process by which cells convert glucose and oxygen into energy, while breathing is the process of inhaling oxygen and exhaling carbon dioxide. Breathing provides the oxygen needed for cellular respiration and removes carbon dioxide.
Step-by-step explanation:
Cellular respiration and breathing are two processes involved in obtaining energy for living organisms, but they are different in terms of their mechanisms and locations.
Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water. It occurs in the mitochondria of cells and involves several steps, including glycolysis, the Krebs cycle, and oxidative phosphorylation.
On the other hand, breathing (also known as ventilation) is the process of inhaling oxygen and exhaling carbon dioxide. It involves the movement of air in and out of the respiratory system, specifically the lungs. Breathing is necessary to provide the oxygen needed for cellular respiration and expel the waste product, carbon dioxide.
