Chapter 16: Cellular Movement
1.
______________________________________ are enzymes that interact with cytoskeletal
proteins to produce motion at the molecular level.
The combined effect of these molecular
motions is to produce motion at the ________________ level.
2.
Motor proteins are powered by _______________________________.
3.
In eukaryotes, components of the cytoskeleton that can interact with motor proteins include
______________________ and _______________________.
4.
Motor proteins that interact with microtubules are called ________________
_____________________.
These are usually involved in transporting ________________ or
__________________ along a microtubule track.
5.
Classes of motor proteins that are associated with microtubules include _______________
and ________________.
6.
Motor proteins move in ___________ direction(s) along their cytoskeletal tracks.
7.
__________________ move their cargo toward the minus end of the microtubule.
8.
__________________ move their cargo toward the plus end of the microtubule.
9.
“Inbound” traffic to the center of the cell requires motor MAPs moving toward the
_______________ end of microtubules.
10. “Outbound” traffic to the periphery of the cell uses motor MAPs that move toward the
_______________ end of microtubules.
11. Microfilament-associated motor proteins include the ______________________.
12. Motor MAPs exhibit __________________________, meaning they can travel long
distances before detaching from the microtubule.
