Understand that cellular respiration is the process by which cells convert biochemical energy from nutrients into ATP, the energy currency of the cell.
Recall that in eukaryotic cells, cellular respiration primarily occurs in a specific organelle specialized for energy production.
Identify the mitochondrion as the organelle where the majority of cellular respiration takes place, including the Krebs cycle and oxidative phosphorylation.
Recognize that other organelles listed, such as lysosomes, Golgi apparatus, and rough endoplasmic reticulum, have different primary functions unrelated to cellular respiration.
Conclude that the mitochondrion is the correct answer because it is the site of aerobic respiration and ATP synthesis in eukaryotic cells.
