The majority of aerobic respiration occurs in the mitochondria, although anaerobic respiration occurs in the cytoplasmic fluid. All three phases of respiration are used to break down carbohydrates: glycolysis, citric acid cycle, and electron transport chain.
The process of creating cellular energy via oxygen is known as aerobic respiration. In the mitochondria, cells break down food in a complex, multistep process that creates 36 ATP. Aerobic respiration is the process of breaking down food that enters a cell while utilising oxygen as a source of energy.
