Transport Through The Cell Membrane

Front 1

Passive Transport

Back 1

doesn't expend ceullular energy for the movemen to take place (like rolling down a hill)

Front 2

3 types of passive transport

Back 2

diffusion, osmosis and facilitated diffusion

Front 3

Diffusion

Back 3

transport of molecules (in general) from an area of high concentration to an area of lower concentration until equilibrium is reached.

Front 4

Solute

Back 4

what gets dissolved

Front 5

Solvent

Back 5

what does the dissolving, more plentiful than solute

Front 6

Solutron

Back 6

mixture of solutes and solvent

Front 7

Osmosis

Back 7

movement of H20 (water...dumbass) from high to low concentration through a membrane untili equilibrium is reached.

Front 8

3 types of solutions (outside of cell)

Back 8

Hypertonic, Hypotonic, isotonic

Front 9

Hypertonic

Back 9

more solute, less solvent

Front 10

Hypotonic

Back 10

less solute, more solvent

Front 11

Isotonic

Back 11

equal amounts of solute/solvent on both sides of membrane

Front 12

Consequences of hypertonic

Back 12

plasmolysis (cell shrinking)
-drinking out of ocean when thirsty
-placing fresh water in salt water (they'll die!)

Front 13

Consequences of hypotonic

Back 13

cytolysis (cell bursting)
-red blood cells in pure water
-salt water fish in fresh water

Front 14

Osmotic pressure

Back 14

osmosis can result in extra water molecules accumulating on one side of the membrane and pressuring the membrane.

Front 15

Facilitated diffusion

Back 15

protein channels in the cell membrane accept only certain particles, like a lock accepts a particular key

Front 16

Pores

Back 16

"two way" protein channels that transport molecules or ions through membrane in either direction. Like an open door that allows you to go in or out.

Front 17

Different _____ particles fit different _____

Back 17

diff. solute particles fit different pores, depending on size, polarity and shape of molecule
