A primary function of cellular respiration is to

Generating ATP from nutrients is the main aim of cellular respiration because every step is geared toward capturing energy to form ATP, the cell’s usable energy currency. Through glycolysis, the citric acid cycle, and oxidative phosphorylation, energy stored in glucose is released in a controlled way and transferred to ATP. That ATP then powers virtually all cellular activities, from muscle contraction to active transport and biosynthesis. While energy is needed for processes like protein synthesis, and DNA stores genetic information while its components include enzymes that can modify DNA, those roles are separate from the primary purpose of respiration.
