The main function of cellular respiration is . View Available Hint(s) The main function of cellular respiration is . making food breaking down toxic molecules making ATP to power cell activities producing cell structures from chemical building blocks

Option C, making ATP to power cell activities

Explanation:

In cellular respiration, the energy stored in food is converted to readily available energy form i.e ATP (Adenosine Triphosphate) molecule. During cell respiration, the cell breakdown the glucose (carbohydrate) molecule into carbon dioxide (CO2), H2Oand ATP (energy molecule).  

ATP being an energy molecule act as a source of energy for all metabolic processes. Along with ATP , higher level energy molecules like NADH is also produced.  

Hence, option C is correct
