The correct answer is D) power company - produces energy.
The Mitochondria produce the energy used by the other parts of the cell - called the ATP - in a process called the Krebs cycle. The Krebs cycle produces ATP - like the energy that a power plant produces and a secondary product is [tex] CO_{23} [/tex], just like typical power plants also produce [tex] CO_{23} [/tex] while producing energy. Both in mitochondria and in power plants, the more energy is produced, the more [tex] CO_{23} [/tex]!
