Answer: Cellular respiration
Step-by-step explanation:
Cellular respiration can be defined as one of the most important mechanism of the living organism by which the energy from the food is converted in the firm which can be used by the body.
The cells can use energy only in the form of adenosine tri phosphate. So, the glucose that is present in the body is converted into adenosine triphosphate in the cell organelle called mitochondria.
Hence, this form of energy is used by the body for various metabolic processes.
