Eukaryotic Cells And Membrane-bound Organelles

Question 1

What are some common organelles?

Answer 1

Nucleus
Endoplasmic reticulum
Golgi apparatus
Lysosomes
Peroxisomes
Mitochondria

Question 2

Where’s ribosomal RNA made?

Answer 2

Nucleolus

Question 3

What keeps the environment within nucleus separate from rest of the cell?

Answer 3

A double membrane called nuclear envelop

Question 4

What do nuclear pores do?

Answer 4

They only allow certain materials to pass through in either direction

Question 5

What are the types of endoplasmic reticulum?

Answer 5

Rough endoplasmic reticulum
Smooth endoplasmic reticulum

Question 6

What does rough endoplasmic reticulum do?

Answer 6

It has ribosomes that allow protein translation

Question 7

What does Smooth endoplasmic reticulum do?

Answer 7

It lacks ribosomes. It’s job is to detoxify drugs and poisons, transport proteins from RER to Golgi apparatus and produce lipids

Question 8

What happens to proteins made by RER?

Answer 8

They’re delivered to Golgi apparatus and might be modified by adding carbohydrates, phosphates, or sulfate

Question 9

What do lysosome do?

Answer 9

Lysosome breaks down the bad substances and gets rid of the waste and dangerous materials to protect the cell

Question 10

What do peroxisomes do?

Answer 10

They use hydrogen peroxide to breakdown long-chain fatty acids that are later used by cell to build phospholipids and sugars

Question 11

How is Mitochondria (energy source that synthesizes ATP) reproduced?

Answer 11

It is unique as it contains its own genes and reproduce via binary fission
