Carrier Protein
|
A protein that transports specific substance through intracellular compartments, into the extracellular fluid, or across the cell membrane.
|
|
|
Concentration Gradient
|
The difference in the concentration of molecules across a space.
|
|
|
Contractive Vacuole
|
Organelles that remove water.
|
|
|
Cytolysis
|
The bursting of cells.
|
|
|
Diffusion
|
The movement of molecules from an area of higher concentration to and area of lower concentration.
|
|
|
Equillibrium
|
When the concentration of molecules of a substance is the same throughout a space.
|
|
|
Facilitated Diffusion
|
Process of which molecules that cannot diffus rapidly through cell membranes.
|
|
|
Hypertonic (Solution)
|
The solution on the outside of cells is higher. (More leaves than come in)
|
|
|
Hypotonic (Solution)
|
The solution on the outside of a cell is slower. (More enters than leaves)
|
|
|
Ion Channel
|
Type of passive transport that involves membrane proteins and ions.
|
|
|
Isotonic (Solution)
|
When the solution is equal inside and outside the cell. (Same enters as leaves)
|
|
|
Osmosis
|
The process by which water molecules diffuse across a membrane.
|
|
|
Passive Transport
|
The movement of such substances across the membrane.
|
|
|
Plasmolysis
|
When a cell shrinks away from the cell walls and turgor pressure is lost.
|
|
|
Turgor Pressure
|
The pressure that water molecules exert against the cell wall.
|
|
|
Active Transport
|
The transfer or movement of materials
|
|
|
Endocytosis
|
The process by which cells ingest external fluid, marcromolecules, and large particles.
|
|
|
Exocytosis
|
The reverse of endocytosis.
|
|
|
Phagocyte
|
Allows lysosomes to fuse with vesicles.
|
|
|
Phagocytosis
|
The movement of large particles or wholes cells.
|
|
|
Pinocytosis
|
Involves the transport of solutes or fluids.
|
|
|
Sodium Potassium Pump
|
A carrier protein found in animal cells.
|
|
|
Vesicle
|
A bubble-like membranous structure that stores and transports cellular products, and digests metabolic wastes within the cell; an intracellular membranous sac that is separated from the cytosol by at least one lipid bilayer.
