Methylparathion and Benthiocarb inhibition of N2 fixation in the cyanobacterium Nostoc muscorum was reversed by Ca(2+) at 1 mM but not at 0.1 mM. The concentration of intracellular Ca(2+) was relatively high in the presence of these pesticides when 1 mM Ca(2+) was also present, indicating that intra

β¦ Synopsis
Ammonium at 5mM completely inhibited nitrogenase activity of Nostoc ANTH but only slightly inhibited the membrane potential, indicating that these two events are independent and that nitrogenase activity is not regulated by the latter.

Many cell types have significant negative resting membrane potentials (RMPs) resulting from the activity of potassium-selective and chloride-selective ion channels. In excitable cells, such as neurones, rapid changes in membrane permeability underlie the generation of action potentials. Chondrocytes
The membrane potential across a composite bipolar membrane (CBM) composed of a cation-exchange membrane with an anion-exchange membrane is theoretically and experimentally analyzed for LiCl ethanol-water solutions. The theoretical approach is based on an extension of the Donnan equilibrium and the N
