Answer:
Cellular respiration is the correct answer.
Explanation:
In respiration, food molecules are broken down to produce chemical potential energy in the form of ATP. It occurs in both animals and plants. In cellular respiration, food molecules such as glucose, which is present in the body is broken down with the addition of oxygen forming carbondioxode, water and energy in the form of Adenine tri phosphate (ATP). This energy is used by the cells in different functions of the body.
