Cell Organelles Flashcards
1
Q
Plasma Membrane
A
Forms a protective barrier and a place for transporters and signaling molecules
2
Q
Nucleus
A
principle site for DNA/RNA synthesis
3
Q
Cytoplasm
A
intermediate for certain metabolism processes like glycolysis
4
Q
Endoplasmic Reticulum
A
(rough or smooth)
protein synthesis, lipid synthesis, protein folding, or Ca2+ storage
5
Q
Golgi Apparatus
A
post-translational changes on proteins or lipids
-important in trafficking molecules-
6
Q
Mitochondria
A
ATP synthesis, signaling, cell differentiation, apoptosis
7
Q
Lysosomes
A
contains digestive enzymes that degrade molecules and organelles
8
Q
Peroxisomes
A
small vesicular compartments that contain enzymes for oxidation
9
Q
Rough ER
A
- flat elongated cisternae studded with ribosomes
- segregation for intracellular use or export from cell
- proteins modified and assembled
10
Q
Smooth ER
A
tubular cistarnae that function in…
- glycogen metabolism
- lipid and membrane synthesis
- detoxification
- steroidogenesis
- Ca2+regulation
