The correct answer is Mitochondria.
Cells use oxygen to release energy stored in the form of glucose. Most of the energy used by the body is released by cellular respiration. This cellular respiration takes place in the organelle called mitochondria. It is present in both plants and animals so both of them release energy by the help of cellular respiration. It releases energy in the form of ATP (adenosine tri phosphate) and regulates the metabolism of the body.
