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.
