The statement that best describes the function of mitochondria is that they convert energy from food molecules into energy the cell can use.
Mitochondria are sites of oxidative respiration. During respiration, food molecules in the form of carbohydrates are broken down to release the energy locked up in them.
The energy, usually in the form of ATP, is utilized by the cell for its metabolism. The entire process of respiration can be summarized according to the following equation:
[tex]6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2[/tex]
