Ion Channels: Structure and Function. Ion channels are membrane protein complexes and their function is to facilitate the diffusion of ions across biological membranes. Membranes, or phospholipid bilayers, build a hydrophobic, low dielectric barrier to hydrophilic and charged molecules. They are electrical insulators.
The inert gas xenon (chemical symbol Xe) has an atomic number of 54, and it has 54 protons in its nucleus. The number of neutrons varies, however.
Xenon is used in Electron tubes, bactericidal lamps, strobe lamps, xenon lamps for surgery, and vehicle headlights (more so in planes and boats). Xenon is used for making el â¦ ectron tubes, stroboscopic lamps, lamps used to excite ruby lasers for generating coherent light.Xenon is also used in the nuclear energy field in bubble chambers, probes, and other applications where a high molecular weight is of value.enon can also be used in flash cameras and high-intensity lamps for projecting movies. Xenon is also used in instruments to detect radiation. Xenon may be used for medicinal purposes as an experimental anesthetic.
