transportation across the cell membrane Flashcards
1
Q
what are the 3 types of passive transport
A
simple diffusion, osmosis, facilitated diffusion
2
Q
what are the two types of active transport
A
vesicular transport, active transport
3
Q
where does simple diffusion and vesicular transport occur
A
channel protein
4
Q
describe osmosis
A
movement of water molecules only
osmosis stops when water molecules are equal on both sides of the SPM
passive transport
5
Q
compare facilitated and simple diffusion
A
facilitated - through carrier protein
simple - through channel protein
6
Q
what is exocytosis
A
when substances are transported out of the cell through a vesicle
7
Q
what is endocytosis
A
when substances are taken into the cell, enclosed in a vesicle
8
Q
what does phagocytosis transport
A
solids
9
Q
what does pinocytosis transport
A
liquids
