transport mechanism Flashcards
large amounts of materials exit cell
exocytosis
transports water and specific ions
channel protein
transports a wide variety of ions and molecules but slower than channel
carrier proteins
movement of molecules from higher to lower concentration
passive transport
cell eating
phagocytosis
helps cell membrane to keep its fluidity
cholesterol - temperature buffer
large amounts of materials enter cell
endocytosis
movement of molecules from lower to higher concentration
active transport
two types of endocytosis
pinocytosis and phagocytosis
primary function of cell membrane
regulate what goes in/out
cell drinking
pinocytosis
three types of carriers
uniporter, antiporter, and symporter
uses ATP to transport molecules
active transport
proteins that allow passage of materials in the cell
transmembrane transports
phospholipid consists of
hydrophobic tail and hydrophilic head
two types of transport mechanism
active and passive
isotonic solution
dynamic equilibrium
types of transport proteins
channel, carrier, and protein pumps
what is used for bulk transportation
large vesicles
hypertonic solution
low water, plasmolysis
movement of water in molecules
osmosis
hypotonic solution
high water, cytolysis
