Q

What does dolichole have on it?

A

sugar trees

17
Q

How does the dolichole get in the lumen?

A

flippase flips it

18
Q

Which proteins does dolichole add sugar tress to?

A

Ones that have the sequence asparagine x-serine theronine

19
Q

Wich way do sugar tress face in the ER?

A

they face the lumen

20
Q

Explain the assembly of the membrane

A

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
