Detailed explanation-1: -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.

Detailed explanation-2: -A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can split glucose into just two molecule s of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide.

Detailed explanation-3: -Cellular respiration that proceeds in the absence of oxygen is anaerobic respiration. Cellular respiration that proceeds in the presence of oxygen is aerobic respiration.

Detailed explanation-4: -Aerobic respiration requires the presence of Oxygen. Note: Aerobic respiration occurs in the cell’s mitochondrial matrix.

Detailed explanation-5: -There are three main steps of cellular respiration: glycolysis; the citric acid (TCA) or the Krebs cycle; and the electron transport chain, where oxidative phosphorylation occurs. The TCA cycle and oxidative phosphorylation require oxygen, while glycolysis can occur in anaerobic conditions.
