The impermeability of the inner membrane to protons is one of the four postulates of the chemiosmotic theory on the coupling mechanism between respiration and phosphorylation in mitochondria. However, oxygen uptake in isolated nonphosphorylating mitochondria requires that protons translocated from

Calcium uptake into filipin-treated bovine spermatozoa is completely inhibited by the uncoupler CCCP or by ruthenium red. Both Pi and mitochondrial substrates are required to obtain the maximal rate of calcium uptake into the sperm mitochondria. Bicarbonate and other anions

The mitochondrial dicarboxylate carrier has been substantially purified from rat liver mitoplasts by extraction with Triton X-114 in the presence of cardiolipin followed by chromatography on hydroxylapatite. Upon incorporation of the hydroxylapatite eluate into phospholipid vesicles, an n-butylmalonate-sensitive malonate/malate exchange
In isolated potato tuber mitochondria, palmitic acid (PA) can induce a H+ leak inhibited by GTP in the phosphorylating (state 3) respiration but not in the resting (state 4) respiration. The PA-induced H+ leak is constant when state 3 respiration

Isolated hepatocytes from hypothyroid, euthyroid and hyperthyroid rats have been employed to investigate the relative importance of reducing-equivalent shuttles for the transfer of hydrogen between cytoplasm and mitochondria during simultaneous ureogenesis and gluconeogenesis. In cells from hypothyroid animals, a 58%
