Answer:
Cellular respiration
Explanation:
Cells get energy from food through the cellular respiration process, which basically consists of the process of extracting the chemical energy stored in glucose molecules, with the participation of oxygen. It is a continuous process that happens in every cell of aerobic beings, both day and night.
In cellular respiration, organic molecules are oxidized and a sequence of reactions occurs to produce ATP (adenosine triphosphate), which is used by living beings to meet energy needs.
If the respiratory mechanism responsible for entry of oxygen gas(O²) is paralyzed in an individual, its cells cease to have the energy necessary for the performance of its vital functions and a process of disorganization of the living matter begins, which causes the death of the individual.
