Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell. Cells that need a lot of energy, like muscle cells, can contain thousands of mitochondria.
Mitchondria are the only sites where true oxidative respiration can occur, they contain enzymes for kreb's cycle, cytochrome complexes for ECT and membranes across which chemiosmosis can occur. All these process can generate as much as 34 ATP molecules from one glucose molecule as opposed to only 2ATP from glycolysis taking place in cytoplasm.
