Document Summary

Chma10 - chapter 8: periodic properties of the elements. Ions carry electric power in the nerve, mainly by na+ and k+. The movement of the ions across the cell membrane is the method of transmitting nerve signals. Na+ and k+ ions are pumped in opposite directions across the cell membranes through the ion pump. The ion pump transmits from low concentration to high concentration. Na+ are transmitted out and k+ are transmitted in. In ion channels, na+ are transmitted in and k+ are transmitted out. The ion channel works from high concentration to low concentration. Na+ and k+ are differentiated by the ion channels and pumps due to the difference in size. Periodic properties: the different properties of atoms in the periodic table described by the position of the element on the table, such as the size of an ion. In an ion pump, the na+ ions are transmitted outside of the cell since the concentration of.
