cell structure and movement Flashcards
1
Q
what structure is a microtubules?
A
hollow tube with a large diameter
2
Q
what structure is a microfilament?
A
two strands twisted around each other with the smallest diameter
3
Q
what structure is the intermediate filaments?
A
thick coiled fibers which has a medium
4
Q
which structure isn’t dynamic?
A
intermiedate filament
5
Q
what proteins move objects along the cytoskeleton filament?
A
motor proteins
6
Q
what two structures act as “tracks” for motor proteins?
A
both microtubules and microfilaments
7
Q
what happens when ATP BINDS TO MOTOR PROTEINS?
A
atp binds to motor protein and the motor protein will break off the posophate group of ATP to release energy
8
Q
functions of microtubules
A
support cell shape
- keep organeles in place
- provide pathwys for organelle and vescile movement
- seperate chromosome during mitosis
- form cillia and flagella in eukaryotes
