Ways to move across the mebranse - Coggle Diagram
Ways to move across the mebranse
by vesicles
lard molecules/proteins /polysaccharides
in
Endocytosis
pinocytosis
phagocytosis
For:big particle;like food
Receptor -mediated
it contains
inside:(ligand/receptor),outside:(coated pit/coated vesicle/coated proteins)
out
Exocytosis
Osmosis
water Diffusion from Hypotonic(moreH2O) to hypertonic(lowH2O)
effectes
Blood cells
in hypertonic solution(lowH2O)
crenation/shrinkage
in hypotonic solution(highH2O)
osmotic lysis/swelling and bursting
Plant cells
in hypertonic solution(low in H2O)
plasmolysis/wilting/shrinkage
no bursting in hypotonic solution because cell wall
freshwater protists
in hypotonic(lhighH2O)
contractile vacuoles discharge water outside the cell
have constant volume
solute movement
Passive transport
Down gradient/No energy
Passive Diffusion
NO transport protein
Small and non charged/like gases
Facilitated Diffusion
with transport protein
big and polar/like:H2O
Active transport
type
Up or down gradient/Need energy+trasporter
primary
direct use of energy
H+ pump ch.5P.42
secondary
use pre-existing gradient
like (Na+/K+-ATPase) ch5.P.43
contain:Antipoeter/Electrogenic pump
