Summary The structural changes of isolated beef-heart mitochondria undergoing hypotonic swelling and ATP-induced contraction are described. During swelling the mitochondria take up water, the matrix space enlarges, the inner membrane becomes greatly extended with material which is apparently derived from the cristae (the rest of which fragment) and the outer membrane is ruptured. On addition of ATP, Mn++ and Ca++ water is extruded as the extended inner membrane contracts around the remnants of the cristae to give compact bundles of vesicles which bear little resemblance to the original organized structure.
