Unit 5: Vesicle mediated uptake

Question 1

what does phagocytosis mean

Answer 1

eat cell

Question 2

pinocytosis mean

Answer 2

drink cell

Question 3

receptor mediated endocytosis

Answer 3

picky eater in cell

receptor= bind specific molecule

Question 4

exocytosis

Answer 4

exit/out cell

Question 5

main function of exocytosis 3 things

Answer 5

• Put things outside (communication)
• add membrane proteins into membrane
• recycle membrane, b/c it’s being stretched

Question 6

when is exocytosis happening

Answer 6

constitutive: always
secretion: put out of cell

Question 7

where does exocytosis happen, direction/ route

Answer 7

Golgi to vesicle to protein membrane

Question 8

protein used with exocytosis

Answer 8

clathrin and snares

Question 9

main function of phagocytosis 2 things

Answer 9

• pseudopodia–> membrane sticking out (made of actin)

- have receptors that recognize patterns

Question 10

main function of pinocytosis 3 thins

Answer 10

1. pinching inward
2. sampling environment
3. use clathrin to punch inward

Question 11

main function of receptor mediated endocytosis 2 things

Answer 11

1. receptor binds specific molecules

2. use clathrin to pinch inward

Question 12

route/ direction of phagocytosis

Answer 12

membrane to vacuole to lysosome

Question 13

size of phagocytosis

Answer 13

Large

Question 14

is Pinocytosis regulated?

Answer 14

no

Question 15

phagocytosis what type of human cells

Answer 15

specific to immune cells

Question 16

Be able to write out exocytosis, pinocytosis, phagocytosis, receptor mediated endocytosis with categories or direction, use ATP, main proteins used, vesicle size, regulated and human cell types

Answer 16

yes
