MITOCHONDRION
- Double-membrane bound: inner membrane invaginates to form cristae
- Space within cristae: matrix (contains free ribosomes)
- Space between inner and outer membranes: intermembrane space
- Synthesizes ATP via citric acid cycle and oxidative phosphorylation (couples oxidation of nutrients with ADP phosphorylation)

Mitochondria
- Cell's "powerhouse."
- Double membrane
- inner membrane comprised of cristae
- The space within the cristae is called the "matrix".
- The space between the outer and inner membranes is called"intermembrane space."
- Synthesize ATP, the cell's energy currency.
- Via the citric acid cycle and oxidative phosphorylation, which is the coupling of two reactions: the oxidation of nutrients and the phosphorylation of ADP.
- They have electron transport chains and enzymes embedded in their inner membrane, which facilitate these reactions.
- Free ribosomes lie within their matrix.
