transport mech..txt

allows nutrients to enter the cell but keep out undesirable substances-

cell providews energy (ATP) to power the transport-

transport process is driven by particle concentration or pressure differences (doesn't use ATP)-

movement of molecules from a region of higher concentration to a region of their lower concentration-

diffusion of solutes through a semipermeable membrane-

diffusion of water through a semipermeable membrane-

affects diffusion-

passive process by which water & solutes are forced through a membrane by hydrostatic pressure; isn't selective-

used to determine glucose (test)-

used to test for silver chloride-
