Mitochondrial transport refers to the movement of molecules into and out of mitochondria, the energy-producing organelles in cells. This process is essential for maintaining cellular function, as mitochondria require specific nutrients, ions, and proteins to generate adenosine triphosphate (ATP), the energy currency of the cell. Transport mechanisms include protein transporters and channels that facilitate the passage of substances across the mitochondrial membranes. These transport systems ensure that pyruvate, fatty acids, and other metabolites enter mitochondria for energy production, while waste products and excess ions are removed to maintain cellular homeostasis.
