Adenosine Triphosphatase Activity of Cauliflower Mitochondria.
Few studIies have been conducted on adenosine triphosphatase (ATPase) in plant mitochondria (3, 5. 6). ATPase activity is important in plant metabolism since it results in the loss of the energy of ATI , and is therefore closely associated with reactions involving phosphorylation and utilization of or requiremiients for ATP. The ternm ATPase is being use(l lhere as defined by Potter (10) to ind...
متن کاملStimulation of Adenosine Triphosphatase Activity Mitochondria and Submitochondrial Particles
Crane and Lipmann (1) have shown that arsenate uncouples oxidative phosphorylation in intact rat liver mitochondria, and that this effect can be reversed by phosphate. They postulated that arsenate competes with phosphate at the site of phosphate uptake. It has also been observed that arsenate can stimulate the respiration of intact mitochondria (1) and of submitochondrial particles’ in the abs...
متن کاملOn the adenosine triphosphatase activity of rat brain mitochondria.
Brain mitochondria are known to differ in many respects from the mitochondria of other tissues in their sensitivity to drugs and to other exogenous factors (l-4) as well as in the nature and organization of their component enzyme systems (5-7). Comparative studies of brain mitochondria may aid in the eventual understanding of the relationship between the special features of brain mitochondria a...
متن کاملInhibition of Adenosine Triphosphatase Activity
Triphenylsulphonium ions inhibit mitochondrial oxidative phosphorylation and adenosine triphosphatase activity. The site of action is on the soluble F1 adenosine triphosphatase component. Triphenylsulphonium ions also inhibit electron transfer in the NAD-cytochrome b region of the respiratory chain. In both types of inhibition, triphenylsulphonium ions are effective at low concentrations, half-...
متن کاملAdrenergic regulation of myosin adenosine triphosphatase activity.
The amount of inorganic phosphate liberated by the adenosine triphosphatase activity of myosin in a thin section of cardiac tissue can be measured quantitatively by precipitation with calcium in an alkaline medium under a defined set of conditions. Specificity of the procedure for myosin adenosine triphosphatase has been confirmed by the response to inhibitors and to different degrees of contra...
