Expert Answer:

Cellular respiration is carried out by mitochondria in each and every living cell in the body.It is the haemoglobin that gets circulated to all of the body via the blood stream. So, the oxygen reaches each and every cell of the body.
And oxygen is required for the cells in our body to breakdown complex food molecules into simpler substances. During this process, energy is released which is utilized for all the cellular and other functions of the body.
