peripheral mem proteins
associate with surface of membrane

usually associated with a integral mem protien
glycocalix
carb chains that project from the outer extra cellular surface of the membrane

usually attached to mem protiens
what is permeable to membrabe
small molecules of water and carbon dioxide

non polar molecules like lipids and steroid hormones
what is impermeable to membrane
ions

polar molecules larger than water

macro molecule of any type
membrane impermeablity
requires specific protiens and mechanisms to transport substances across membrane
diffusion
molecules spread from an area of greater concentration to lesser conc.
transport protiens
gate movement of particles across the membrane
four ways a substance can move across membrane
simple of passive diffusion

facilitated diffusion

active transport

endo and exocytosis
simple or passive diffusion
occurs when a substance moces down the conc gradient and across the membrane with the help of aprotien
facilitated diffusion
specific trasport protiens allow movement down the conc grad across membrane

driving force
active transport
use of atp
exocytosis
secretion from cell
endocytosis
movement into cell
