TransportVOCAB ONLY
An INTEGRAL MEMBRANE PROTEIN that moves molecules PASSIVELY across cell membranes by attaching, CHANGING SHAPE, and flipping to the other side like a revolving door
Carrier protein
A state that exists when the CONCENTRATION of a substance IS THE SAME throughout a space
equilibrium
http://bio.winona.edu/berg/ANIMTNS/Directry.htm
Kind of endocytosis used to take in large particles or whole cells.
phagocytosis
The DIFFUSION of WATER across a semi-permeable MEMBRANE osmosis
The pressure of water pushing against the cell wall in a plant cell is called ________________ pressure.
LABEL THE DIAGRAMS:
osmotic
HYPERTONIC HYPOTONICISOTONIC
Solution in which the
solute concentration outside
the cell is LESS than inside
hypotonic
Movement of molecules ACROSS a cell membrane from an area of LOWER concentration to HIGHER concentration using ENERGY
Active transport
The swelling and bursting of an animal cell when placed in a HYPOTONIC solution
cytolysis
An INTEGRAL MEMBRANE PROTEIN that provides a passageway/tunnel across the cell membrane through which WATER molecules can diffuse PASSIVELY during osmosis
Aquaporinshttp://www.spps.kvl.dk/news/0507/Lund4.jpg
Solution in which the
solute concentration outside
the cell is greater than inside
hypertonic
Molecule used by cells to provideenergy for active transport
ATP
Solution in which the
solute concentration outside
and inside a cell are EQUALisotonic
Sodium-potassium pump
Kind of active transport that can move sodium and potassium ions quickly AGAINST the concentration gradient
A process in which the cell
membrane surrounds and engulfs
substances and pulls them into the cell
endocytosis
An INTEGRAL MEMBRANE PROTEIN that provides a passageway/tunnel across the cell membrane through which IONS can diffuse PASSIVELY
Ion channel
A membrane thatlets certain molecules pass
through and not others is called_______________Semi-permeable OR
selectively permeable

A process in which a VESICLE inside a
cell fuses with the cell membrane and
releases its contents OUTSIDE the cell
EXOCYTOSIS

iodine
Substance that turns blue-black when it reacts with starch
___________ transport does NOT require energy to move molecules across membranes.
Passive
The process by which molecules MOVE from an area of HIGHER concentration to an area of LOWER concentration
diffusion
http://www.estrellamountain.edu/faculty/farabee/biobk/BioBooktransp.html
The shrinking away of the cell membrane from the cell wall in a plant cell when placed in a HYPERTONIC environment
plasmolysis
Organelle that uses exocytosis totransport molecules out of the cell
Golgi (body) apparatus
A small membrane bound sac in a eukaryotic cell used to transport substances around within a cell or during exocytosis or endocytosis
The shrinking of animal cells when placed in a hypertonic solution is called ______________
vesicle
crenation
Organelle that makes the ATP used to run active transport?
mitochondria
Type of endocytosis in which cellstake in small molecules or fluids
pinocytosis
mass of a dissolved substance in a given volume
concentration
The difference in the concentrationof molecules across a space
Concentration gradient
Image by Riedell
Solution in which the
solute concentration outside
and inside the cell is equal
isotonic
A MEMBRANE PROTEIN that uses energy to ACTIVELY transport hydrogen ions (H+)across a cell membrane
PROTON PUMP
Process that REQUIRES ENERGY to move molecules across a cell membrane against a concentration gradient (moves molecules from lower concentration → higher concentration)
Active transport
Movement of specific molecules across cell membranes with the help of protein channels and carriers
Facilitated diffusion
