Endomembrane System

Question 1

TRUE OR FALSE: Phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc. In fact, any phospholipid may be called a “cellular tourist” because it is able to move about to virtually any part of a cell and can even become a part of a cell in a different region of the body!

Answer 1

True

Question 2

What cell organelle synthesizes phospholipids?

Answer 2

Smooth ER

Question 3

What cell organelle modifies the protein molecule?

Answer 3

Golgi body/apparatus

Question 4

What cell organelle location of translation for proteins destined to be secreted from the cell?

Answer 4

Rough ER

Question 5

What cell organelle stores and protect the DNA?

Answer 5

Nucleus

Question 6

What cell organelle exocytosis to release the modified protein out of the cell?

Answer 6

Cell/Plasma Membrane

Question 7

What cell organelle RNA moves through me to get to the rough ER?

Answer 7

Nuclear Pore

Question 8

What cell organelle transport the modified protein to the cell membrane?

Answer 8

Vesicle

Question 9

A protein “coat” aids the budding vesicles from membranes. What is the name of the protein?

Answer 9

Clathrin

Question 10
