Lec 10

Question 1

Smoothe er is made of

Answer 1

tubes

Question 2

Rough ER is made of

Answer 2

Flattened sheets covered in ribosomes

Question 3

ER synthesizes

Answer 3

Lipids

Phospholipids

Glycolipids

Cholesterol for the whole cell

Question 4

ER to nuclear envelope

Answer 4

Lateral diffusion/sliding over to nuclear envelop

Question 5

ER to rest of endomembrane system

Answer 5

Moving through vesicles to reach lysosomes golgi and plasma membrane

Question 6

Delivery to semi-autonomous organelles

Mitochondrion

Peroxisome

Answer 6

Phospholipid exchange proteins

Phospholipid grabs the lipid and moves it to the organelles

Net movement is from the ER to the mitochondrion because the mitochondrion uses the cargo

Question 7

Plants have chloroplasts which use

Answer 7

Phospholipid exchange proteins

Question 8

Some proteins are made by

Answer 8

Free ribosomes

Question 9

If a protein is destined for the cytosol it is

Answer 9

Delivered upon being made

Question 10

Proteins have

Answer 10

Signals for organelle delivery

Question 11

Import into ER requires a

Answer 11

Signal from a protein

Question 12

Export proteins requires

Answer 12

Just ER signaling

Goes from inside the ER to outside the cell

Question 13

Membrane protein transport

Answer 13

Needs ER signal + tran-membrane domains

Question 14

How do chloroplasts move proteins

Answer 14

Free ribosomes + import
