cell transport Flashcards
in or out of the cell?
-nutrients
-water
-oxygen
-amino acids
-ions
IN
in or out of the cell?
-toxins
-carbon dioxide
-urea
-hormones
-enzymes
OUT
what are the two main components needed to regulate the flow of liquids and dissolved gas in/ out of the cell?
phospholipid bilayer and channel/carrier proteins
what type of transport are diffusion and osmosis?
passive transport
what type of transport is the sodium potassium pump, endocytosis, exocytosis and phagocytosis?
active transport
the movement of particles from and area of high concentration to an area of low concentration
diffusion
the movement of water from an area of high concentration to an area of low concentration
osmosis
cells that have shrivelled due to too much salt going in meaning water going out
hypertonic
what are normal cells that have the correct amount of water called?
isotonic
why are swollen/ burst cells that have too much water in them called?
hypotonic
the type of transport that requires energy
active transport
what is it called when material gets exported out of the cell via the vesicle
exocytosis
what is it called when material gets imported to the cell through the plasma membrane
endocytosis
what is it called when the cells plasma membrane surrounds a molecule in the extra cellular environment and closes to form a vacuole
phagocytosis
what is it called when solutes bind to the cell membrane then starts to fold inwards until both ends meet producing a pinosome
pinocytosis
