In order for cellular respiration to take place, mitochondria must have oxygen. Mitochondria are the building blocks of the cell, and the cell cannot survive without it.
Mitochondrium - this is the part of the cell responsible for the supply of energy in the form of ATP (adenosine triphosphate). Neurons need an enormous amount of energy. The brain is one of the most metabolically active tissues in the body. In man, for example, the brain uses 40 ml of oxygen per minute. Mitochondria use oxygen and glucose to produce most of the cell's energy. The brain consumes large amounts of ATP.
