The primary function of cellular respiration is to generate ATP (a catabolic pathway), which traps some of the chemical energy of food molecules in its high- energy bonds (adenosine triphosphate). The process of generation of ATP is via glycolysis and Krebs’s cycle finally through oxidative phosphorylation. Fermentation is another catabolic pathway that mediates generation ATP anaerobically in muscle cell.
The overall balanced reaction of cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
Glucose + oxygen → carbon dioxide + water + energy
Thus, the options (a), (b) and (d) are incorrect.

Therefore, the correct option is – c. fermentation and cellular respiration.
