passive and active transport

Question 1

passive transport

Answer 1

does not required expenditure of energy by the cell 
simple diffusion 
osmosis
facilitated diffusion 
bulk flow( filtration)

Question 2

simple diffusion

Answer 2

goes right through the cell (flows form an area of high conc. to an area of low concentration

Question 3

osmosis

Answer 3

water follows salt-

Question 4

isotonic

Answer 4

both salt and water are at equal amounts

Question 5

hypotonic

Answer 5

to little salt and too much water moves into cell causing it to hemolyzed and burst.

Question 6

hypertonic

Answer 6

too much salt compare to solvent (water) this causes the cell to move water out of the cell and it shrinks (crenated)

Question 7

facilitated diffusion

Answer 7

ion and protein channel along the membrane

Question 8

filtration( bulk flow )

Answer 8

requires a difference in pressure ( hydrostatic pressure in blood vessels )

Question 9

active transport

Answer 9

the usage of energy from the splitting of ATP. moving molecules across cell membrane against conc gradient

Question 10

Membrane pumps

Answer 10

primary and secondary

Question 11

primary

Answer 11

hydrolyses from ATP
changes the shape of transport of media
(sodium/pump ion channel )

Question 12

secondary

Answer 12

uses potential energy in an ionic conc.
Antiporter - move Ca+ out of the cell
Symporter- moves substances in like glucose

Question 13

Endocytosis

Answer 13

moves stuff into the cell by vesicles many types of endocytosis.

Question 14

phagocytosis

Answer 14

endocytosis of large particles- cell eating

Question 15

pinocytosis

Answer 15

endocytosis of ECF tha contains dissolved solutes (cell drinking)

Question 16

receptor mediated endocytosis

Answer 16

ligands bind to cell membrane, receptor mediated endocytosis brings to specific receptors into cell

Question 17

Exocytosis

Answer 17

substances are removed from the cell
examples are nerve cells to release neurotransmitters
digestive enzymes, protein
