Cellular Transport

TermDefinition
Carrier Protein Protein that changes shape to move particles
Cell membrane Organelle in charge of maintaining homeostasis
Selective Permeability Choosing certain molecules to pass through
Concentration Gradient unequal distribution of particles
phospholipid molecule makes up cell membrane has polar heads and nonpolar tails
exocytosis cell membrane moves around vessicle to release particles
Cell Wall prevents plant cells from bursting in a hypotonic solution
Active Transport uses ATP to move particles from low to high
Passive Transport type of transport that does not need energy to move particles from high to low
Osmosis movement of only water across the membrane from high to low
Simple Diffusion movement of gasses from High to Low
Facilitated Diffusion movement of particles from high to low through a channel protein
Endocytosis cell membrane moving around a particle to bring it in uses ATP
Hypotonic Solution Water moves in blowing up cell
Hypertonic Solution Water sucked out of cell causing it to shrink
Isotonic Solution Water moves in and out b/c cell in equalibrium
Channel Protein Protein that looks like a tunnel
