Lipophilic cations (tetraphenylarsonium, tetraphenylphosphonium, and triphenylmethylphosphonium) caused a number of major changes in the physiology of Bacillus subtilis. Macromolecular synthesis was inhibited, adenosine 5'-triphosphate concentration increased, swimming speed was reduced, tumbling was suppressed, and the capacity to take up the

Tetraphenylarsonium (TPA+) inhibited energy transduction in oxidative phosphorylation in mitochondria but not in submitochondrial particles, which are inside-out relative to the membranes of mitochondria. TPA+ incorporated into the inside of submitochondrial particles inhibited ATP synthesis in the particles. TPA+ also

The lipophilic anion tetraphenylboron (TPB-) but not the lipophilic cation tetraphenylarsonium (TPA+) inhibited ATP-dependent Ca2+ accumulation by isolated sarcoplasmic reticulum. TPB- did not inhibit ATP hydrolysis but did induce Ca2+ release from preloaded vesicles. It did not appear to disrupt

In order to elucidate the mechanism of action of organochlorine insecticides on the ion transport in biological membranes, we have studied the effect of DDT and its analog DDE on the structural parameters of phosphatidylethanolamine (PE) planar bilayers. DDT and
