Identify the process in question: cellular respiration, which is the metabolic pathway that converts biochemical energy from nutrients into ATP, the energy currency of the cell.
Recall that cellular respiration involves multiple stages, including glycolysis, the citric acid cycle, and oxidative phosphorylation.
Understand that glycolysis occurs in the cytoplasm, but the majority of cellular respiration, especially the citric acid cycle and oxidative phosphorylation, takes place inside a specific organelle.
Recognize that the mitochondrion is the organelle responsible for the citric acid cycle and oxidative phosphorylation, making it the primary site of cellular respiration in eukaryotic cells.
Eliminate other options: the Golgi apparatus is involved in protein modification and sorting, lysosomes in digestion and waste processing, and the rough endoplasmic reticulum in protein synthesis, none of which are the main sites of cellular respiration.
