The oxidation-reduction potential of cytochrome b of heart muscle was estimated by Ball (1938) to be -40mv at pH 7-4 and 250. Since then it has become increasingly evident from the work of Chance (1952a, b) on the kinetics of the respiratory chain and from measurements by Hill (1954, and personal communication) that the true value of the potential is likely to be considerably more positive. In ...

Mitochondria, the major site of synthesis for energy rich phosphate bonds in animal tissues, have been alluded to as the ionic pumps in cells because of the action of energy rich compounds in the control of osmotic properties (1, 2). Since the work of Raaflaub (3, 4) there have been several reports (1, 5-8) that adenosine triphosphate plus magnesium or manganous ions can reverse or prevent swel...
