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
