Question
Chapter 23.4, Problem 1CC
Summary Introduction
To analyze:
The filament moves more like the arms of a human swimmer or the shaft of a boat propeller.
Introduction:
Bacterial flagella allow bacterial cells to move by gliding, twitching, or swimming in liquids at the rate of more than 150 µm per second. The bacterial flagellar filament is a helical assembly of single protein flagellin that helps in bacterial locomotion.

Intermediate filaments are composed of?
If you were to watch muscle tissue contract:
Under a light microscope, would you see the muscle fibers get narrower, or the striations get thinner? Explain.
At the EM level, focusing on one sarcomere, you would be able to see a region of thick filaments overlapping two regions of thin filaments. Use the structure of the thick filaments to explain how ONE region of thick filaments is able to pull in microfilament in two opposite directions (both toward the center of the sarcomere).
How is filament polarity detectable?
