Explanation:

- Lungs: Organs in the respiratory system. They help in oxygen exchange and remove carbon dioxide from the bloodstream. Not involved in cellular energy production.

- Pituitary glands: Known as the "master gland." It produces hormones that regulate various body functions. It does not generate cellular energy.

- Arteries: Blood vessels that carry oxygen-rich blood from the heart to the rest of the body. They are part of the circulatory system, not involved in energy production at the cellular level.

- Mitochondria: Known as the "powerhouses" of the cell. They generate ATP, the cellular energy currency, through oxidative phosphorylation.
