Yes. There are two forms of cellular respiration- aerobic respiration and anaerobic respiration. The main purpose of cellular respiration is to produce energy. The energy that is formed by cellular respiration is in the form of a molecule known as ATP, which stands for adenosine triphosphate. The energy within ATP is housed within its high-energy phosphate bonds. Aerobic respiration utilizes mitochondria. There are three stages to aerobic respiration- glycolysis, the Krebs cycle (which is sometimes refered to as the citric acid cycle), and the electron transport chain. Each stage utilizes a different part of mitochondria. Aerobic respiration uses glucose and oxygen to create water, carbon dioxide, and up to 38 ATP. On the other hand, anaerobic respiration occurs in the cytoplasm (or cytosol). Anaerobic respiration does not utilize oxygen as a reactant. Anaerobic respiration is not as efficient in the production of ATP as is aerobic respiration. Anaerobic respiration only produces a net yield of 2 ATP.
