Study Notes
- Mitochondria are organelles in eukaryotic cells that produce ATP.
- Proteins are transported into mitochondria through translocator complexes.
- Matrix proteins are directly transported across interacting outer and inner membrane translocators.
- Cristae contain four protein complexes that harvest electrons from carriers.
- Electron transport in Complexes II, III, and IV is coupled with proton pumping, creating an electrochemical gradient called the proton motive force.
- ATP synthase uses the proton motive force to synthesize ATP.
- ATP/ADP carrier is responsible for the coordinated import of ADP and export of ATP across the inner membrane.
- Mitochondria move alongside microtubules and can undergo dynamic changes in shape.
- Perturbations in mitochondrial behavior and membrane permeability are associated with programmed cell death.
- Mitochondria are distributed near sites of high demand for ATP and other metabolites.
