WebB. Identify the characteristics that play a role in the electrical signals created by nervous tissue. Select all that apply. Specific channels alter membrane permeability to ions. Semipermeable membranes help create a separation of ions. Electrical charges are separated across the cell membrane. Denticity (represented by κ) refers to the number of times a ligand bonds to a metal through noncontiguous donor sites. Many ligands are capable of binding metal ions through multiple sites, usually because the ligands have lone pairs on more than one atom. Ligands that bind via more than one atom are often termed chelating. A ligand that binds through two sites is classified as bidentate, and three sites as tridentate. The "bite angle" refers to the angle between the two bon…
