2.3.5: Cytosis Flashcards
1
Q
what is cytosis
A
a form of bulk transport that requires ATP
2
Q
what is it called when a cell engulfs small molecules in solution
A
pinocytosis
3
Q
what is it called when a cell engulfs large solid molecules
A
phagocytosis
4
Q
describe the process of cytosis
A
endocytosis -> endosome (vesicle) -> secretory vesicle -> exocytosis
5
Q
what effect does endocytosis have on the surface area of a cell
A
decreases the surface area
6
Q
why does cytosis occur
A
substances that are too big to pass through the membrane, pass by cytosis
7
Q
what does the membrane of a cell need to be for cytosis to occur
A
needs to be fluid to move/engulf/fuse, cholesterol is responsible for membrane fluidity
