Mitochondria function: Mitochondria are double membrane-bound

Mitochondria are double membrane-bound cell organelles with a typical size of 0.75-3 μm². They are found in most mammalian cells, with notable exceptions including mature erythrocytes. Classically referred to as the 'powerhouse of the cell', they are the site of the majority of ATP synthesis and are therefore exceptionally important to function both microscopically and macroscopically.In this article we will look at the function and structure of mitochrondria, and consider some clinical ... Mitochondria are the critical structures of the cell composed of double membranes responsible for energy production. Explore 6 major mitochondria functions . Mitochondria are membrane-bound organelles in eukaryotic cells responsible for producing adenosine triphosphate (ATP), the primary energy currency of the cell. Mitochondrion, organelle found in most eukaryotic cells, the primary function of which is to generate energy in the form of adenosine triphosphate. Mitochondria also store calcium for cell signaling activities, generate heat, and mediate cell growth and death.
