The interactions of cobalt(II) with mitochondria from rat liver.

The interactions of Co(2+) with mitochondria have been investigated. The results indicate that Co(2+) inhibits ATP synthesis. Further investigations into ATP synthesis mechanisms indicated that inhibition is due to the opening of a transmembrane pore. The opening of this pore causes the collapse of the high-energy intermediate where, under a pH and a potential gradient, the energy is stored and subsequently utilized to form ATP from ADP.
