Verified step by step guidance

Understand the concept of aerobic respiration: Aerobic respiration is a process in which cells generate energy (ATP) by breaking down glucose in the presence of oxygen. It involves multiple stages, including glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation.
Identify the organelle responsible for energy production: In eukaryotic cells, the mitochondria are known as the 'powerhouses' of the cell because they are the primary site of ATP production during aerobic respiration.
Break down the stages of aerobic respiration: Glycolysis occurs in the cytoplasm, but the citric acid cycle and oxidative phosphorylation, which are key components of aerobic respiration, occur within the mitochondria.
Eliminate incorrect options: Ribosomes are involved in protein synthesis, not energy production. The nucleus contains genetic material and regulates cellular activities but does not play a direct role in aerobic respiration. The cytoplasm is where glycolysis occurs, but it is not the primary site of aerobic respiration.
Conclude that the mitochondria are the correct answer: Based on the information above, aerobic respiration primarily takes place in the mitochondria of eukaryotic cells.
