Eukaryotic Structures Flashcards
1
Q
Microfilaments
EC
A
- has dynamic instability
2
Q
Intermediate filaments
EC
A
- Diverse monomers
- Doesn’t have dynamic instability
3
Q
Microtubules
EC
A
- 2 monomers
- has dynamic instability
4
Q
Dynamic instability
EC
A
- Growing and shrinking
- Allows the cell to rapidly reorganize the cytoskeleton when necessary
5
Q
Extracellular matrix
EC
A
- This is outside of the cell; what is happening outside the cell.
- Holds the cell together
- Regulating the behavior of cells in multicellular organisms
- Could also be written as: Regulates a cells dynamic behavior
- Dynamic behavior = cell behavior overtime
Provides structural support to cells and tissues
6
Q
Cell junctions
Tight
EC
A
Prevent substance from through spaces between cells
EX: intestines
7
Q
Cell junctions
Gap
EC
A
Channel between membrane pores
EX: heart muscle cells
8
Q
Cell junctions
Desmosomes
EC
A
- Hold cells together together but material can still move around in extracellular matrix
- Linked to intermediate filaments
EX: skin
EC
