Cellular respiration is the process by which organisms convert glucose and oxygen into energy in the form of ATP. There are two types of cellular respiration: aerobic respiration, which requires oxygen and produces more ATP, and anaerobic respiration, which does not require oxygen but produces less ATP. The byproducts of aerobic respiration are carbon dioxide and water, while the byproduct of anaerobic respiration in humans is lactic acid. Respiration occurs in organisms via different respiratory structures suited to their environment, such as lungs in humans and tracheal systems in insects.
