WebThe silver ion is known to inhibit glutathione peroxidase and NA+,K+-ATPase activity, respectively disrupting selenium-catalyzed sulfhydryl oxidation-reduction reactions and intracellular ion concentrations. Silver nanoparticles are believed to disrupt the mitochondrial respiratory chain, causing oxidative stress, reduced ATP synthesis, and DNA ... WebAn axon with a larger diameter offers less resistance to the movement of ions down the axon, causing ions to move faster down the axon and causing the action potential to be conducted faster. Let me show you the way I think about this by just considering a single sodium ion that's entering an axon through a voltage-gated sodium channel.
