Golgi Apparatus

Question 1

What is the Golgi apparatus?

Answer 1

organelle responsible for sorting and addressing

Question 2

Define: target sorting

Answer 2

sorting into specific vesicles

Question 3

Define: default sorting

Answer 3

non-specific sorting

Question 4

What is the addressing domain?

Answer 4

its where the trans end of the Golgi label where things go

Question 5

Define: exocytosis

Answer 5

vesicles leave the cell

Question 6

What happens to the membrane of vesicles that leave the cell?

Answer 6

They get added to the plasma membrane

Question 7

What are COP coats?

Answer 7

coltmer proteins that help form vesicles

Question 8

What do coltmer proteins transport?

Answer 8

they are non-specific and move anything through the cisternae

Question 9

What coating does the sorting domain have?

Answer 9

clathrin coat

Question 10

What are T-snares?

Answer 10

they are the addresses

Question 11

What are V-snares?

Answer 11

they are the envelopes

Question 12

Define: fusogens

Answer 12

they fuse the membrane

Question 13

What is the cis face?

Answer 13

its the part of the Golgi where membranes will fuse with the Golgi

Question 14

How do vesicles get to the trans face?

Answer 14

they travel from cisternae to cisternae until they reach

Question 15

Define: dolichole

Answer 15

lipid in the membrane built in the cytoplasm

Question 16

What does dolichole have on it?

Answer 16

sugar trees

Question 17

How does the dolichole get in the lumen?

Answer 17

flippase flips it

Question 18

Which proteins does dolichole add sugar tress to?

Answer 18

Ones that have the sequence asparagine x-serine theronine

Question 19

Wich way do sugar tress face in the ER?

Answer 19

they face the lumen

Question 20

Explain the assembly of the membrane

Answer 20

phospholipids are in a watery environment, so they bind to CoA which is hydrophilic and a glycerol and phosphate is added and then they are inserted into the membrane
