## Abstract The effects of Tl^+^ ions on isolated rat liver mitochondria were studied in the presence of nonactin, a cyclic ionophore. Nonenergized rat liver mitochondria were increasingly swollen at an elevated concentration of Tl^+^ in the 160 mOsm medium containing 0β150 mM sucrose and 0β75 mM T
Effects of Cd β«2β¬ and two complexes of bivalent cadmium with 1,3-bis(4-chlorbenzylidenamino)-guanidine and anabasine on ion permeability of the inner membrane and respiration of isolated rat liver mitochondria were studied. Starting from 5 lM, Cd β«2β¬ decreased state 3 and DNP-stimulated respiration
Citrinin depresses the phosphorylation efficiency of rat renal cortical mitochondria, as inferred from the decrease of the respiratory control coefficient (RC) and ADP/O ratios. The transmembrane potential (A+) developed by energized mitochondria and the depolarization upon ADP addition are also dec
## Abstract The influence of piperine on the enzymes and bioenergetic functions in isolated rat liver mitochondria and hepatocytes was studied. Piperine at lower concentrations (<50 ΞΌM) did not affect the RCR and ADP:O ratios, state 4 and 3 respirations supported by siteβspecific substrates, viz. g
