Detailed explanation-1: -Aerobic Respiration: It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food.
Detailed explanation-2: -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.
Detailed explanation-3: -Oxygen is an essential requirement for aerobic respiration but it has role only at the terminal stage of the process. Oxygen drives the whole process by removing hydrogen from the system. Oxygen acts as the final acceptor of hydrogen.
Detailed explanation-4: -A chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also called aerobic metabolism, cell respiration, and oxidative metabolism.
Detailed explanation-5: -Why oxygen? Oxygen is the final ele ctron ac ceptor at the end of the electron transport chain of aerobic respiration. In the absence of oxygen, only a few ATP are produced from glucose. In the presence of oxygen, many more ATP are made.
