Cell Structure

Question 1

What does smooth ER do? What’s the different between rER and sER?

Answer 1

Synthesize lipids. sER doesn’t have ribosomes attached.

Question 2

What does rough ER do? What organelles are attached to it?

Answer 2

Manufactures proteins with help of ribosomes to export out of the cell. Sits around nucleus and has ribosomes attached to make proteins.

Question 3

What does Golgi apparatus do?

Answer 3

Protein modification and export. Also manufactures lysosomes.

Question 4

What is the function of lysosomes? Where are they manufactured?

Answer 4

Protein, lipid, nucleic acid, and carbohydrate destruction. Also destroy viruses which infect the cell.

Manufactured in the Golgi apparatus.

Question 5

What are the 4 types of vesicles.

Answer 5

1. Transport vesicles- move things throughout cell
2. Lysosomes- break down things
3. Peroxisomes- use oxygen to break down toxic things in cell
4. Secretory vesicles- holds things to be secreted like waste and hormones.

Question 6

What organelle moves to opposite sides of the cell during prophase?

Answer 6

Centrioles.

Question 7

What are ribosomes?

Answer 7

Help manufacture proteins on the rough ER.
