Transport protiens
channel protiens
carrier protiens
transport protiens
membrane protiens
peripheral protiens
intergal proteins
cell transport
passive transport requires no energy
Active transport needs energy
energy active transport
carrier protiens
active transport
hypotonic and hypertonic
A solution is hypertonic if the solute concentration is greater than that inside the cell
A solution is hypotonic if the solute concentration is less than inside the cell
membrane proteins and their functions
a membrane is a collage of different prteins often clustered in groups, embedded in the fluid matrix of the lipid bilayer
This structure resembles a tile mosaic
Peripheral proteins
are bound to the surface of the
membrane
Integral proteins
penetrate the hydrophobic core
Transmembrane proteins
are integral proteins
that span the membrane
cell surface membrane proteins
Transport
– Enzymatic activity
– Signal transduction
– Cell-cell recognition
– Intercellular joining
– Attachment to the cytoskeleton and extracellular
matrix (ECM)
Osmosis
is the diffusion of free water across a selectively permeable membrane
Tonicity
is the ability of a surrounding solution to
cause a cell to gain or lose water
endocytosis
macromolecules are taken into the
cell in vesicles
three types of endocytosis
Phagocytosis (“cellular eating”)
– Pinocytosis (“cellular drinking”)
– Receptor-mediated endocytosis
exocytosis
transport vesicles migrate to the membrane, fuse it and release their continents outside shell
