Flashcards in Organelles Deck (11):
0

Mitochondria

-Lipids are metabolized
-Own DNA (circular)
-From maternal line
-The Endosymbiotic Theory states that they came from a prokaryote and worked themselves into the eukaryotes.

1

Rough ER

-Covered ribosomes
-Makes proteins for plasma membrane, endosomes, Golgi, lysosomes and rough ER.

2

Smooth ER

-Lipid synthesis/modification

3

Golgi Apparatus

-Packs and ships proteins
-continues post-translational modification
-ships to either plasma membrane, back to the ER, or to organelles

4

What two places can you find DNA in the cell?

-Nucleus
-Mitochondria

5

What's the shape of the DNA in the mitochondria? In the nucleus?

Mitochondria - Round
Nucleus - Helix

6

In the mitochondria the PH of the intermembrane space is more (acidic/basic) than the matrix?

Acidic

7

Centrioles/centrosome

-Organizes microtubules, flagella and cilia
-Plays a key role in cell division.

8

Lysosomes

-ph of 5
-digest cell parts
-fuse phagocytotic vesicles
-participate in cell death
-form by budding off Golgi

9

Peroxisomes

-Self-replicate
-Detoxify chemicals
-Participate in lipid metabolism

10

Name all the layers to get to the nuclear lumen.

Cell membrane (2 layers)
Outer nuclear membrane (2 layers)
Inner nuclear membrane (2 layers)
