Chapter 16
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.
