Active Transport
what is used to transport the molecules out of the cell
exocytosis
second type of passive transport
osmosis
Which one is permeable a metal sink or a brick wall
what is a brick wall
cell membrane
controls movement in and out of cell
facilitated diffusion
molecules moving through a membrane using transport protiens
what is used to transport molecules into a cell
endocytosis
third type of passive transport
facilitaded diffusion
what is permeable
something that is permeable is able to have things pass through its membrane
passive transport
the movement of substances through a membrane without using energy
solute
thing being dissolved
how does endocytosis work
a cell surrounds a substance with cell membrane arms and closing it off
the first type of passive transport and example
diffusion , dropping food coloring in cup of water
semi permeable
when only some things can pass through membrane
active transport
the process of moving substances through a membrane using energy
solvent
thing doing the dissolving
the process of exocytosis
a vesicle attaches to the membrane and opens it up and causes it to become shape of membrane
the protein used to take things in and out of cell
transport protiens
non permeable
membrane that is not able to be passed through
molecules moving from high to low concentration
dipole
2 charges
what is something that can be compared to active transport
pushing a ball up a hill
two types of transport cells
carrier and channel
is a paper permeable
yes
osmosis
water molecules diffusing through a membrane
macromolecule
a big molecule made of smaller ones
