<unk> s (also known as "voltage-gated<unk> s") are integral membrane proteins that conduct sodium ions (Na+) through a cell's plasma membrane. Many of the ionotropic receptors are also able to conduct sodium ions. In excitable cells such as neurons and myocytes,<unk> s are responsible for the rising phase of action potentials.
