Organelles Flashcards
0
Q
Rough ER
A
- Covered ribosomes
- Makes proteins for plasma membrane, endosomes, Golgi, lysosomes and rough ER.
1
Q
Mitochondria
A
- 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.
2
Q
Smooth ER
A
-Lipid synthesis/modification
3
Q
Golgi Apparatus
A
- Packs and ships proteins
- continues post-translational modification
- ships to either plasma membrane, back to the ER, or to organelles
4
Q
What two places can you find DNA in the cell?
A
- Nucleus
- Mitochondria
5
Q
What’s the shape of the DNA in the mitochondria? In the nucleus?
A
Mitochondria - Round
Nucleus - Helix
6
Q
In the mitochondria the PH of the intermembrane space is more (acidic/basic) than the matrix?
A
Acidic
7
Q
Centrioles/centrosome
A
- Organizes microtubules, flagella and cilia
- Plays a key role in cell division.
8
Q
Lysosomes
A
- ph of 5
- digest cell parts
- fuse phagocytotic vesicles
- participate in cell death
- form by budding off Golgi
9
Q
Peroxisomes
A
- Self-replicate
- Detoxify chemicals
- Participate in lipid metabolism
10
Q
Name all the layers to get to the nuclear lumen.
A
Cell membrane (2 layers)
Outer nuclear membrane (2 layers)
Inner nuclear membrane (2 layers)
