Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
A mitochondrion is a round to oval-shaped organellefound in the cells of almost all eukaryoticorganisms. It produces energy, known as ATP, for the cell through a series of chemical reactions.
Known as the “powerhouses of the cell,” mitochondria produce the energy necessary for the cell's survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes. In addition to producing energy, mitochondria store calcium for cell signaling, generate heat, and are involved in cell growth and death.
