Answer: CELLULAR RESPIRATION
Step-by-step explanation:
Cellular respiration is defined as the oxidation (break down in the presence of oxygen) of organic food substances within the cell leading to the release of energy, carbon dioxide and water.
It can be represented by the equation:
C6H12O6 + 6O2 --> 6H2O + 6CO2 + Energy (in form of ATP)
Thus, the main purpose of cellular respiration that takes place in a cell is to generate energy required by the whole body.
