Chapter 7 Transport of ions in solution and across membranes
www.physiome.orgThe transport of ions across cell membranes is essential to life. Most of it is passive, due to electrical and chemical concentration differences. The electrochemical potential difference is the key to excitation of the cells, for it governs the opening and closing of channels and drives ionic
Estimates of Ionospheric Transport and Ion Loss at Mars
