Detailed explanation-1: -Because oxygen is required for cellular respiration, it is an aerobic process. Cellular respiration occurs in the cells of all living things, both autotrophs and heterotrophs. All of them catabolize glucose to form ATP.
Detailed explanation-2: -Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.
Detailed explanation-3: -Why do cells need oxygen? Aerobic cells and organisms need oxygen in order to perform aerobic cellular respiration. Oxygen is the end electron acceptor in the electron transport chain, and is necessary to maintain the flow of electrons and thus create the hydrogen ion gradient needed for ATP synthase to function.
Detailed explanation-4: -One that takes place in presence of oxygen is called aerobic respiration. Aerobic respiration requires the presence of oxygen to produce energy from food. It is the most common type of respiration seen in plants and animals.
