Organelles in the cells of which the oxygen stage of cellular respiration takes place is called …

This stage takes place inside the mitochondria. In order to receive energy, a cell must carry out three stages of energy metabolism. This is a preparatory, oxygen-free and oxygen-free stage. During the oxygen phase, energy is released in the course of organic matter. This requires oxygen, which is why this stage is called “breathing”. Carbohydrates, fats and proteins are capable of oxidizing. Proteins are oxidized only when there are no carbohydrates and fats left in the cell. The main part of the energy is received by the cell during the oxidation of carbohydrates.
