Respiration is the process by which living organisms take in oxygen and release carbon dioxide. This process is essential for life and occurs in all living cells.
Here's a breakdown:
* Cellular respiration: The process by which cells convert glucose (sugar) into energy (ATP) using oxygen.
* Breathing: The physical act of taking in oxygen and releasing carbon dioxide through the lungs. This is often referred to as "pulmonary respiration" and is closely tied to cellular respiration.
