Cytoskeleton Flashcards
1
Q
Where are microfilaments found?
A
In the cell cortex (found under the cell membrane surface) and in bundles in microvilli (absorptive cells in the intestine).
2
Q
What are Microtubules made of?
A
Tubulin.
3
Q
Where are Microtubules found?
A
They extend from the centrosome.
4
Q
What is the purpose of Microtubules?
A
They have an important role in the structure of the cell and in the movement of organelles.
5
Q
What is the purpose of capping proteins?
A
To stabilise Microtubules which have not reached the cell cortex or bound to organelles.
6
Q
Why is the position of capping cell important?
A
The position of the capping proteins determines the shape of the cell as Microtubules bind to capping proteins.
7
Q
What are micro filaments made of?
A
Actin. Sometimes they’re called actin filaments.
