Cell membrane transport

Abstract:

Cell membrane transport is a process by which chemicals and other substances move across cell membranes. Animal cells are bound by an outer membrane that, in accord with the fluid mosaic model, consists of a phospholipid bilayer interspersed with proteins. These protein molecules act as receptor sites. There are a variety of channels in the membrane (as well as a number of internal cellular membranes) that partially partition the intercellular matrix. These internal membranes ultimately become continuous with the nuclear membrane. There are three principal means by which molecules can pass through the boundary cellular membrane; these are the mechanisms of outer cellular membrane transport. They are passive diffusion (also called gradient diffusion), facilitated diffusion, and active transport. (download to read more)
