Which cellular structure is the powerhouse of the cell due to aerobic metabolism?

• A. Nucleus
• B. Ribosome
• C. Cytoplasm
• D. Mitochondria

Answer: (D)

Mitochondria are the site where energy from nutrients is converted into ATP through aerobic respiration. They house the TCA cycle and the electron transport chain, using oxygen to drive oxidative phosphorylation and produce the majority of the cell’s ATP. The nucleus stores genetic material, ribosomes are the protein factories, and the cytoplasm is the fluid where many reactions occur (including glycolysis) but the efficient ATP production from aerobic processes happens in mitochondria. This makes them the powerhouse of the cell.
